    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.
