<p>There is provided a honeycomb structure 1 obtained by unitarily bonding a plurality of honeycomb segments 3 having a plurality of cells separated and formed by porous partition walls and extending through between two end faces 11, 12 with a bonding material 5 in a direction perpendicular to an axial direction of the cells. At least a part of the bonding material 5 extending in the axial direction of the cells in a cross section in parallel with the axial direction of the cells of the honeycomb structure 1 has continuously increasing thickness from the end portions toward a central portion in the axial direction of the cells. In the honeycomb structure, without raising pressure loss, thermal shock resistance is improved by enhancing thermal stress relaxation ability in the central portion in the axial direction.</p> |
