To provide a manufacturing method of a ceramic honeycomb structure capable of preventing a partition from chipping in processing the end face of the ceramic honeycomb structure with a cup-type abrasive wheel.

The manufacturing method of a ceramic honeycomb structure comprises the step of processing the end face of the ceramic honeycomb structure having a large number of cells formed by porous partitions by using the cup-type abrasive wheel. The cup-type abrasive wheel has a step on the outer peripheral side end face to the inner peripheral side end face at the axial direction attaching part side of the cup-type abrasive wheel, that the cup-type abrasive wheel has an abrasive particle layer at a grinding part thereof, and that the abrasive particle layer is composed of abrasive particle layers having different particle size each other with regard to the outer peripheral side and the inner peripheral side, that is, an abrasive particle layer having a relatively larger particle size is formed at the outer peripheral side and an abrasive particle layer having a relatively smaller particle size is formed at the outer peripheral side.
