ABSTRACT:
A honeycomb structure has a plurality of honeycomb segments each including porous partition walls that define a plurality of cells communicating with two end surfaces and an outer wall that surrounds the partition walls. The honeycomb segments are combined in a direction perpendicular to the axial directions of the honeycomb segments, and the outer walls of the honeycomb segments are integrally joined by a joint material. The outer wall of each honeycomb segment has corners. A cell in contact with the inner surface of a portion of the outer wall having one of the corners is defined by a plurality of sides including two sides formed by the inner surface and two sides each having one end in contact with the inner surface. An angle θa of the corner formed by the two sides each having the one end in contact with the inner surface is 100 to 150°.
