(57) [Summary] [PROBLEMS] While containing refractory particles such as silicon carbide particles, it can be manufactured at a relatively low firing temperature at a low cost, and Honeycomb whose thermal conductivity is set to an appropriate value, is sufficiently porous and has a high specific surface area, and can be suitably used as a filter for purifying automobile exhaust gas even under high SV conditions by processing such as plugging and carrying a catalyst. Provide a structure. SOLUTION: This honeycomb structure has a large number of flow holes penetrating in the axial direction partitioned by partition walls, and includes a refractory particle 11 serving as an aggregate and metallic silicon 10, and is a porous honeycomb structure. It is. |
