The Interval exchange map generalizes the irrational rotation of the circle. We discuss Diophantine type of the irrational rotation to the interval exchange map and introduce a Diophantine type for the interval exchange maps using the asymptotic rate of the return time. It is a generalization of the Roth's type condition for the irrational rotation. Also the asymptotic rate of hitting time is considered.
