EXHAUST GAS PURIFICATION FILTER AND ITS USE IN AN EXHAUST PASSAGE OF A GASOLINE ENGINE
An exhaust gas purification filter (1) is configured to be disposed in an exhaust passage of 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 parts (13) that alternately seal ends of the plurality of cells (12) in the exhaust gas purification filter. The exhaust gas purification filter (1) is, with an average pore diameter of the partition wall (11) as A(µm) and an average surface opening diameter of the pores (110) at a surface of the partition wall as B(µm), adapted such that A ≥ B is satisfied, with A of 5 µm or more and less than 15 µm, and such that a proportion calculated from a formula of 100 × (A - B)/B is 30% or less.
