EXHAUST GAS PURIFICATION FILTER
An exhaust gas purification filter (1) is configured to be disposed in an exhaust passage in a gasoline engine. The exhaust gas purification filter (1) includes partition walls (11) including a plurality of pores (110), a plurality of cells (12) partitioned by the partition walls (11), and sealing portions (13) alternately sealing ends of a plurality of the cells in the exhaust gas purification filter. The partition walls (11) each has a pore surface area of 100,000 m2/m3 or more in the partition wall (11), and satisfy A ≥ B where A(µm) is an average pore diameter of the partition wall (11), and B(µm) is an average surface opening diameter of the pores (110) in a partition wall (11) surface.
