The arrival of the Brazilian forward marks the fourth signing for Arsenal this summer window.
Jesus has scored 95 goals in 233 competitive appearances for the Cityzens and has won the Premier League, FA Cup, League Cup and Community Shield during his five-year spell.
The 25-year-old striker explained why he chose to move to the Emirates this summer.
“First of all, [I need] to adapt,” he told GOAL. “Adapt to the club, adapt with the players, the way they play and the way they are.
“After this, everything else will come naturally. This is football. Football is the same everywhere. Then at the end of the season I want to win something.
“Win trophies. Like everybody here at Arsenal. That is the only way to make myself a name in the history of this big club. It is a big club with a big project.
“When Edu explained to me what they want for the future, I was so excited to join Arsenal because I love the project. I want to win trophies. I want to win everything.”
