(57) [Summary] [PROBLEMS] To reduce the thermal stress generated in a honeycomb structure due to a rapid change in inflow gas temperature during use, local reaction heat, and combustion heat, thereby preventing the honeycomb structure from being destroyed. To provide a honeycomb structure excellent in durability and reliability. SOLUTION: This is a honeycomb structure 1 in which a plurality of honeycomb segments 2 each having a honeycomb structure having a large number of flow holes 6 penetrating in an axial direction partitioned by partition walls are integrated. One or more honeycomb segments 2 (a) that do not constitute the outermost peripheral surface 23 of the honeycomb structure 1 Outer peripheral surface 21 and honeycomb segment 2 adjacent thereto A honeycomb structure 1 characterized in that a compression elastic material A3 is disposed between the honeycomb structure 1 and (b). The honeycomb structure 1 Is a honeycomb structure assembly 8 formed by compressing and holding a compression elastic material B5 on the outermost peripheral surface 23 of the honeycomb structure 1 in the metal container 11. |
