    In porous partition walls of the honeycomb structure, there are formed large pores which show one distribution a in a graph illustrating a pore diameter distribution and in which a pore diameter PP1 at a maximum peak value v1 of pore volumes of the one distribution a is 12 µm or more, and small pores which show the other distribution b in the graph illustrating the pore diameter distribution and in which a pore diameter PP2 at a maximum peak value v2 of pore volumes of the other distribution b is smaller than the pore diameter PP1, the pore diameter PP1 and the pore diameter PP2 satisfy a relation of 0.91 ≤ (PP1-PP2)/PP1 ≤ 0.98, and a ratio of the pore volume of the pores having pore diameters smaller than the pore diameter PP2 to a total pore volume of the partition walls is 0.5% or more and 7% or less.

    Abstract: An exhaust gas purification filter includes an inflow/outflow passage through which exhaust gas flows in/out, and a partition. The outflow passage and the inflow passage is alternately arranged. The partition is configured to divide the inflow passage and the outflow passage from each other, and being porous. The partition includes a coated zone where a surface of a base of the partition is covered with a first coating layer having an average pore diameter smaller than an average pore diameter of the base, and a non-coated zone where the surface of the base is not covered with the first coating layer on a downstream side of the coated zone. The average pore diameter of the base is large enough for ash to pass through the partition, and the first coating layer is constituted by a plurality of particle groups with different average particle diameters from each other.
