    Abstract: Formation is performed so that an opening percentage of the first cells 5a may increase continuously or in stages from the first cells 5a in a central portion in the cross section toward the first cells 5a in a peripheral portion excluding incomplete cells in an outermost periphery in the cross section. Specifically, the partition wall between the first cell 5a and the first cell 5a is formed to have a large thickness. In addition, the difference in the opening percentage between the first cell 5a and the second cell 5b is made small. A honeycomb segment and a honeycomb structure of the present invention can inhibit crack generation due to a heat spot generated by the difference of thermal conductivity.
