Abstract

See full text

Provided is an exhaust purification filter that is able to reduce pressure loss and that has high exhaust purification performance and particulate matter trapping performance. This exhaust purification filter comprises a filter substrate having a wall flow structure, and an exhaust purification catalyst supported on a partition wall of the filter substrate. The volume-based median pore diameter (D50) of the filter substrate is 18 μm or greater, the full width at half maximum of the pore distribution of the filter substrate is 7 μm to 15 μm, and the exhaust purification catalyst is supported in an unevenly distributed manner in a high-density layer in which the density of the exhaust purification catalyst is relatively high and a low-density layer in which the density of the exhaust purification catalyst is relatively low.
