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.
