PURPOSE:To enable regenerative efficiency and durability to be improved and also to facilitate the temperature control in regeneration by raising temperature without temperature nonuniformity in a short period. CONSTITUTION:One exhaust emission control device 10 is constituted by combining and arranging twelve pieces of filters 3, 4 formed into a honeycomb shape by a porous silicon carbide sintered body. Heaters 5 as a heating element are provided on the outer peripheral part of the filters 3, 4. A seal member 8 serving as a heat resistant filling material is interposed between the filters 3, 4 adjacent to each other, and its periphery is covered by a heat insulating member 9. |
