Abstract: A honeycomb structure includes a pillar-shaped honeycomb structure body having porous partition walls, wherein the partition walls have projecting portions, in the cells of 10% or more of the plurality of cells, the projecting portions project into the cells, a tip curvature radius R of an apex of each of the projecting portions is from 0.01 to 0.1 mm, side surfaces of the projecting portions are inclined to the surfaces of the partition walls at an inclination angle of 40 to 70°, and a relation of 0.04≤H/A≤0.4 is satisfied.

Abstract: The honeycomb structure is equipped with a pillar-shaped honeycomb structure body having a porous partition wall that defines a plurality of cells extending from an inflow end face to an outflow end face and serving as a through channel of a fluid and a circumferential wall placed to surround the circumference of the partition wall. The honeycomb structure body has, in a face orthogonal to an extending direction of the cells of the honeycomb structure body, a circumferential cell structure, a center cell structure, and a boundary wall placed at a boundary between the circumferential cell structure and the center cell structure and incomplete cells of 5% or more to 50% or less of the total number of the incomplete cells of the center cell structure is communicated with incomplete cells of the circumferential cell structure with each other.

Abstract: A pillar-shaped honeycomb structure body of a honeycomb structure includes a circumferential cell structure, a central cell structure and a boundary wall therebetween. On a surface orthogonal to the cells there are a circumferential reinforcing region having the partition wall thicker than a basic partition wall thickness in the circumferential cell structure and existing outside a range of a distance from a centroid of the surface; and at least one of a first boundary reinforcing region having the partition wall thicker than the basic partition wall thickness and existing in a range of a distance from the centroid within a range of the circumferential cell structure and a second boundary reinforcing region having the partition wall thicker than a basic partition wall thickness in the central cell structure and existing outside of a range of a distance from the centroid within a range of the central cell structure.
