摘要：There is provided a honeycomb filter wherein particles having an averageparticle diameter smaller that of the particles constituting partition walls are depositedat least in open pores formed by the particles constituting the partition walls and/or

gaps between the particles in a surface layer portion of the partition walls on the exhaustgas inflow side, thereby forming a composite region. The average pore diameter of thepartition walls is 5 to 40 μm, and the porosity of the partition wall is 35 to 75%. Theparticles to be deposited have an average particle diameter of 1 to 15 μm, and the heightof the composite region is not more than 80 μm in the direction from the outermostcontour line of the partition walls to the surface of the partition walls.
