Abstract
The honeycomb structure includes a pillar-shaped honeycomb structure body having porous partition walls, as to the honeycomb structure body, in a plane perpendicular to a cell extending direction, a cell structure of a central cell structure differs from a cell structure of a circumferential cell structure, and in the plane, a geometric center of gravity of the honeycomb structure body exists at a position which is away from a geometric center of gravity of the central cell structure, and a distance between the respective centers of gravity is larger than a length of a half of a cell pitch of an outermost circumferential cell structure including complete cells formed at an outermost circumference of the honeycomb structure body.
