The Dane is to start Sunday's derby against AC Milan.
Conte said, “We brought in Eriksen because he has characteristics that suit our style of football. Italy is far more tactical than in other leagues, so he'll need some time to get adjusted to the changes.
“I hope he doesn't need too long, because we need him. He is an intelligent player who understands football, so we're very pleased to have him."
Eriksen is the fifth player Conte has signed from the Premier League.
“I had a great experience in England, one of the most important leagues in the world. You can find many talented players there and in this case, we found the best opportunities to pick up players from the Premier League.
“It was a tactical decision, partly for their quality, but also their intensity."
