发明名称 Exhaust gas purifying filter with reinforced peripheral area and method for manufacturing the same
摘要 An exhaust gas purifying filter having a high strength and an excellent efficiency of exhaust gas purification and a method for manufacturing the same are provided. An exhaust gas purifying filter 1 comprises a ceramic honeycomb structure 2 having a surrounding wall 21, partition walls 22 provided in a honeycomb pattern within the surrounding wall 21, and a plurality of cells 23 partitioned by the partition walls 22 and penetrating through end faces 241, 242. If a virtual line 3 is drawn on the end faces 241, 242 of the structure 2 by continuously connecting points at a distance of 1.0 to 3.0 times the cell pitch in the direction toward the center from an inner surface 211 of the surrounding wall 21, not less than 90% of a peripheral area 25 outside the virtual line 3 is blocked with plug material 4.
