The 27-year-old has signed a three-year deal with Ipswich.
“I enjoyed my time at Cardiff but this is a new start for me at Ipswich and I’m looking forward to it,” he told the club’s official website.
“I spoke to the manager and was impressed with his plans for the club. I know some of the players here as well and from talking to them, it was clear there is real ambition at Ipswich.
“I can’t wait to get going and the target is to help the club reach the Premier League.”
“Michael is a top quality striker with a proven track record when it comes to scoring goals,” said Ipswich manager Paul Jewell.
“He is just the type of player we are looking for to help take this club forward.”
Town chief executive Simon Clegg added: “We’re obviously delighted to have added Michael to the squad. It’s a signing that I’m sure will excite our supporters.”
