A honeycomb structure includes a ceramic block including at least one honeycomb fired body. The at least one honeycomb fired body has cell walls and a peripheral wall. The peripheral wall is formed around the at least one honeycomb fired body. The peripheral wall of the at least one honeycomb fired body, which forms a periphery of the ceramic block, is a stepped peripheral wall provided with a level difference. The level difference includes a projected portion and a recessed portion in a cross section perpendicular to a longitudinal direction of the at least one honeycomb fired body. At least one of the projected portion and the recessed portion is formed by at least one of a curve line and a straight line in the cross section perpendicular to the longitudinal direction of the at least one honeycomb fired body by being subjected to chamfering.

A honeycomb structure includes a ceramic block including at least one honeycomb fired body. The at least one honeycomb fired body has cell walls to define cells and a peripheral wall constituting a periphery of the at least one honeycomb fired body. The cells include peripheral cells in contact with the peripheral wall of the at least one honeycomb fired body constituting a periphery of the ceramic block and basic cells arranged at an inner side of the peripheral cells. The peripheral cells include deformed cells each having a different shape from the basic cells in a cross section perpendicular to a longitudinal direction of the at least one honeycomb fired body. Each of the deformed cells is capable of receiving therein a circle of about 0.9 mm in diameter in the cross section perpendicular to the longitudinal direction.
