摘要： An electric heating type support includes: a pillar shaped honeycomb structure being configured to a ceramic, including: an outer peripheral wall; and partition walls disposed on an inner side of the outer peripheral wall, the partition walls defining a plurality of cells, each of the cells extending from one end face to other end face to form a flow path; at least one electrode layer disposed on a surface of the outer peripheral wall of the pillar shaped honeycomb structure; and at least one electrode connecting portion provided on the at least one electrode layer, the at least one electrode connecting portion being connectable to a metal connector. The at least one electrode connecting portion has at least one independent rising portion, and a height of the at least one electrode connecting portion from a surface of the at least one electrode layer is from 1 to 6 mm.

摘要： A honeycomb structure has a pillar-shaped honeycomb structure body having porous partition walls which defines cells which forms a passage of liquid extended from an inflow end face toward an outflow end face, a circumferential wall arranged to surround a circumference of the partition walls. The honeycomb structure body has an outermost circumference cell structure including a complete cell arranged at the outermost circumference of the honeycomb structure body, a center cell structure formed by the cells arranged at a center part at an inner side to the outermost circumference cell structure, and a boundary wall arranged at a boundary part between the outermost circumference cell structure and the center cell structure. The outermost circumference cell structure and the center cell structure are formed as different structures to each other, and a thickness of the boundary wall is set to be thicker than a thickness of the circumferential wall.
