Abstract: The honeycomb filter 10 is constructed as a diesel particulate filter (DPF) having a filtration function for filtering out the PM (particulate matter) included in an exhaust emission of a diesel engine. The honeycomb filter 10 has a honeycomb structure 12 as a base and inlet opening cells 16 with surface layers 26 formed on respective inner surfaces thereof. The surface layer 26 has zero film thickness in an inlet peripheral region 28. Separation vortexes are generated in the inlet peripheral regions 28. The zero film thickness of the surface layers 26 in the inlet peripheral regions 28 naturally causes non-flaking of the surface layers 26 induced by the separation vortexes generated in the inlet peripheral regions 28 and thereby leads to non-production of flakes. In the non-existent condition of flakes, the overall surface layers 26 are not collapsed by collision of the flakes.

Abstract: In a plugged honeycomb structure 1A of the present invention, the PM-trapping layers 14 disposed on the surfaces of the partition walls 4 are extended up to inflow side end faces of the plugging portions 13 plugging outflow cells 3b so that adjacent PM-trapping layers 14 with the partition walls 4 and the plugging portion 13 therebetween are disposed so as to continue on the inflow side end faces of the plugging portions 13 and that the PM-trapping layers 14 extended up to the inflow side end faces of the plugging portions 13 form protruding portions 15 having a protrusion height corresponding with 0.1 to 2 times the length L of a side of the outflow cells 3b from the inflow side end faces of the plugging portions 13 toward the outside of the cell extension direction.
