Claim 0:
1. A method for producing a ceramic honeycomb structure, the honeycomb structure comprising: an outer peripheral wall; a partition wall arranged on an inner side of the outer peripheral wall, the partition wall defining a plurality of cells each extending from one end face to other end face to form a flow path, the honeycomb structure having a slit that divides the honeycomb structure in a cross section orthogonal to an axial direction of the honeycomb structure,
wherein the method comprises:
a first step of preparing a honeycomb structure being free from slit, and forming the slit leaving at least a part of the outer peripheral wall;
a second step of filling, after the first step, the slit with a joining material; and
a third step of removing, after the second step, at least a part of the outer peripheral wall left in a linear direction of the slit formed in the first step to obtain the honeycomb structure having the slit that divides the honeycomb structure.
