Abstract

An exhaust purification filter is provided that can efficiently purify HC, CO and PM. An exhaust purification filter (1) includes: an oxidation catalyst zone (Z1) formed by loading a Pt-containing oxidation catalyst that oxidizes HC and CO on an upstream-side portion of a filter main body (10); a PM oxidation catalyst zone (Z3) formed by loading an Ag-containing PM oxidation catalyst that oxidizes PM on a downstream-side portion; and a gap zone (Z2) that is formed between these catalyst zones in which a catalyst is not loaded, characterized in that a gap rate (=G/ (L-D) x100) is less than 15%, in which a length in an exhaust flow direction of the exhaust purification filter (1) is L, a length in the exhaust flow direction of the oxidation catalyst zone (Z1) is D, and a length in the exhaust flow direction of the gap zone (Z2) is G.
