摘要： Provided is an exhaust gas purification catalyst in which the performance of a catalyst metal can be brought out properly, the purification catalyst boasting excellent purification performance during warm-up of an internal combustion engine. The exhaust gas purification catalyst 10 is provided with a substrate 1 and a catalyst layer. A leading end section 1a positioned upstream in the direction of exhaust gas flow (arrow) has a portion in which the flow rate of exhaust gas is relatively high and a portion in which the flow rate of exhaust gas is relatively low during warm-up of the internal combustion engine. The catalyst layer in the portion of relatively high flow rate of exhaust gas has a high density section 6 in which a noble metal is supported at relatively high density. The high density section 6 is formed to be shorter than the total length of the exhaust gas purification catalyst 10 from the leading end section 1a in the direction of exhaust gas flow.

The catalyst-coated filter (2) includes a filter substrate (21) and a catalyst layer (22) on a pore wall of the filter substrate (21). The catalyst-coated filter (2) has a first end portion, a second end portion, a filter wall (21W), an entry-side cell, and an exit-side cell. The filter wall (21W) is porous. The entry-side cell is opened at the first end portion and closed at the second end portion. The exit-side cell is opened at the second end portion and closed at the first end portion. The entry-side cell and the exit-side cell are adjacent to each other with the filter wall (21W) interposed therebetween. The inorganic particles (3) in a powder form are localized at a surface of the filter wall (21W) adjacent to the entry-side cell at a cross section parallel to the thickness direction of the filter wall.
