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 have an average pore diameter of more than 16 µm and less than 21 µm, and have a ratio of an average surface opening diameter of the pores in a partition wall surface to the average pore diameter of the partition wall of 0.66 or more and 0.94 or less.
