Honeycomb Structure

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. 本发明提供蜂窝结构体，其有效抑制了在蜂窝结构体外周侧形成的孔格的变形，且机械强度优异。所述蜂窝结构体具备柱状蜂窝结构部，所述蜂窝结构部具有划分形成多个孔格的多孔质隔壁，所述孔格从流入端面延伸至流出端面并成为流体流路，蜂窝结构部中，在与孔格延伸的方向正交的面上，中央孔格结构与外周孔格结构为不同的孔格结构，所述外周孔格结构由在比中央孔格结构靠外侧的外周部分形成的多个孔格构成，在与孔格延伸的方向正交的面上，蜂窝结构部的几何重心与中央孔格结构的几何重心存在于相离的位置，且各重心间的距离大于最外周孔格结构的孔格间距的半长度，所述最外周孔格结构包含在蜂窝结构部的最外周形成的完
