    摘要: An exhaust gas purification filter 100 includes: a honeycomb structure 10 having partition walls 12, plugging portions 13, and a surface trapping layer 14 having an average pore size of 0.1 μm or more and 5 μm or less, a porosity of 50% or more and 80% or less, and a thickness of 1 μm or more and 50 μm or less. The partition walls 12 have a thickness of 0.05 mm or more and 0.18 mm or less and an average pore size of 10 or more and 18 μm or less, and the proportion of the volume of the pores having a size of twice the average pore size or more in the entire pore volume in a pore size distribution of the partition walls 12 is 5% or more and 40% or less.
