An exhaust gas purification filter (1) includes a plurality of cells (11) extending in a filter axial direction (X), a porous partition (12) separating and defining the plurality of cells (11), and a sealing section (13) sealing the plurality of cells (11) alternately at both filter ends. In the exhaust gas purification filter (1), the partition (12) has a void volume of a reduced dale (123), Vvv, and a material volume of a reduced peak (124), Vmp, as volume parameters determined in noncontact surface roughness measurement on a surface of the partition (12), with their total value being 1.8 µm3/µm2 or less.
