Abstract:
1. A honeycomb structure comprising: a bonded honeycomb segment article in which bond surfaces of a plurality of honeycomb segments are integrally bonded to one another via bonding material layers; and an outer peripheral coating layer which coats an outer peripheral surface of the bonded honeycomb segment article, the honeycomb structure having a structure in which a plurality of cells forming fluid channels are arranged in parallel with one another in a central axis direction, wherein the honeycomb segments are bonded via the bonding material layers, and wherein the bonding material layers occupy less than a whole bond region by occupying entire surfaces of the bond surfaces and including portions filled with bonding material and a hollow portion therein so that the bonding material layers occupy less than the whole bond region of the bond surfaces; and wherein each portion filled with bonding material is disposed toward an outer portion of the whole bond region of each segment, so as to cover regions within a range, from respective opposite ends toward the center in the central axis direction of the whole bond region, at each end, of a length occupying thirty percent or less of a length of the whole bond region, the filled portions total not exceeding sixty percent of the length of the whole bond region, and wherein a bond region is formed between respective two adjacent honeycomb segments.
