<p>A honeycomb structure having honeycomb segments integrally joined together at the outer walls thereof by a jointing material containing inorganic particles. The honeycomb segments each have an entrance-side end face on the fluid entrance side, an exit-side end face on the fluid exit side, outer walls for interconnecting the outer peripheral sections of the two end faces, and cells located on the inner side of the outer walls, the cells being partitioned and formed between the two end faces by partition walls, which consist of a porous body, and functioning as fluid flow paths. The average distance (S) between local crests on the surfaces of the outer walls is 10 to 140 µm, the arithmetic average surface roughness Ra of the surfaces of the outer walls is 0.4 to 23.5 µm, and the average diameter of the inorganic particles is 0.5 to 30 µm.</p> |
