The 18-year-old, who can play either as a centre-back or as a defensive midfielder, featured just five times last season under former Blues boss Maurizio Sarri.
New Chelsea manager Frank Lampard revealed recently he tried to sign Ampadu on loan in January when he was in charge at Derby.
The move to RB Leipzig will be Ampadu’s first loan spell since his arrival at Stamford Bridge from Exeter two years ago.
Ampadu has made 12 appearances in his two years with Chelsea and in September 2018 he signed a new five-year contract.
Chelsea are banned from signing players during the next two transfer windows until the end of January 2020, which could have opened up an opportunity for Wales international Ampadu this season.

New head coach Lampard, though, feels the move to Germany will prove beneficial for all parties.
“I tried to sign Ethan on loan at Derby last year so I’m a big fan,” Lampard said on the Chelsea website.
“But with the minutes he played last year, in the interest of Ethan and of Chelsea, the idea he can play a lot of games somewhere could be good for him.
“I really wanted to work with Ethan this year. That’s a slight disappointment, but it’s to benefit of him.
“In midfield and defence we have a lot of quality, so each player is a case by case.”
Ampadu believes the switch will prove the ‘perfect step’.
“I’m delighted to be at RB Leipzig and can’t wait to start the season with my new team. I want to get to know the lads and integrate into the team as quickly as possible,” he said on Leipzig’s website.
“I have followed the club in recent years and have seen how well young players have developed here and how much potential this club has, so it’s the perfect step for me.”
Chelsea lost 1-0 to J League side Kawasaki Frontale in their pre-season friendly in Yokohama.
Lampard will now prepare his squad for the Rakuten Cup clash against Barcelona in Saitama on Tuesday.
Chelsea midfielder N’Golo Kante will not feature as he has returned to England to continue rehabilitation for an injury connected to a knee problem sustained at the end of last season.
New Derby County manager Phillip Cocu feels it will ‘difficult but not impossible’ to bring in Chelsea trio Mason Mount, Fikayo Tomori and Ethan Ampadu on loan this summer.
Former Netherlands international Cocu is the club’s first ever foreign manager and has signed a four-year contract to succeed Frank Lampard.
Derby acted quickly to find a replacement for Lampard, who left after one season at Pride Park to take over at his former club Chelsea.
Much of the success Derby had under Lampard, in which they narrowly missed out on reaching the Premier League, came from the impact of on-loan stars Mount and Tomori, who was named Derby’s player of the year.

“It will be difficult I think. I don’t say impossible,” Cocu replied when asked about the chances of bringing them back to Derby.
Aston Villa’s promotion to the Premier League was met with jubilant celebrations and sighs of relief from large sections of the West Midlands.
Dean Smith’s side beat Derby County 2-1 at Wembley to end a three-year exile from the top flight, but the boyhood Villa fan instantly set about building a squad capable of staying up as soon as the champagne had dried off his suit.
Club-record signing Wesley Moraes is expected to be confirmed on July 1 once work permit issues have been ratified, with the 17-goal striker making his £22million move from Club Brugge official.
Smith is still working hard to bring Tyrone Mings back to the club, with the Daily Express claiming the Villans want to add six more signings to their squad.
Jack Butland of Stoke is an option in goal, with Ethan Ampadu, Leeds star Kalvin Phillips and Brentford winger Said Benrahma also under consideration.

With John McGinn and Jack Grealish set to stay after superb seasons in the Championship, Villa could quite easily have a squad capable of challenging for a top half finish in the Premier League.
So how could Smith’s starting XI for next season look? Check it out below.
Last season, Smith alternated between a 4-3-3 formation and a 4-4-1-1, depending on who the opposition was. If, for instance, they were playing a more defensive team at home, Smith would drop Grealish back into midfield alongside McGinn and Glenn Whelan.
This would allow Villa to attack from deep and get their playmakers on the ball to create chances for former loanee Tammy Abraham up front and then supply into the wide areas where the full backs were given license to roam past their inverted wingers.
While Whelan and Neil Taylor performed dutifully last year, the introduction of Phillips into midfield and Matt Targett from Southampton at left-back adds greater mobility to the side.
If, however, they play sides who expect to dominate the ball and will try to pass Villa to death, Smith can implement a 4-4-1-1 formation to solidify his team, with Grealish playing in a more advanced role to feed off scraps from the lone striker.
Aston Villa have made enquires about bringing talented Chelsea star Ethan Ampadu on loan ahead of next season, reports claim.
The 18-year-old played just five times last season and did not feature once in the Premier League under Maurizio Sarri and Chelsea are keen for the versatile defender to get more experience.
Villa boss Dean Smith wants to sign a defensive midfielder following the decision to release experienced duo Glenn Whelan and Mile Jedinak and the Wales international is more than capable of playing in that role.
The former Exeter City midfielder would be tempted by a switch and will be helped in his decision with former Chelsea captain John Terry, assistant manager at Villa.

Smith is leading a huge summer overhaul of his squad, with Anwar El Ghazi, Jota and Kortney Hause already signing on the dotted line this summer, while eight players have been released following their return to the top-flight.
Aston Villa are also keen on signing Stoke and England keeper Jack Butland this summer, while Tyrone Mings, who impressed during a loan spell in the second half of last season at Villa Park, is another player the newly-promoted side have their eye on – but a move for the 26-year-old is not expected to be imminent.
Chelsea wonderkid Ethan Ampadu has been linked with a January loan move to Aston Villa or Derby.
The Championship rivals are said to be keen on signing Ampadu, the Wales international, on a temporary basis when the transfer window reopens.
The versatile 18-year-old, who can play in midfield or defence, has already made seven first-team appearances for Chelsea, though he has failed to play in any matches this term.
A recent injury has kept Ampadu out of action over the past few weeks, and Maurizio Sarri’s refusal to loan the youngster out over the summer had many suggesting he would be playing him relatively frequently.

Aston Villa are also said to have wanted the youngster, and the Birmingham Mail say both clubs will return for Ampadu when the transfer window opens in January.
