Abstract: An exhaust gas cleaning catalyst that has: a substrate having a wall flow structure, wherein an entry side cell, in which the end part on an exhaust gas inflow side is open, and an exit side cell, in which the end part on the exhaust gas outflow side is open, are divided by a porous dividing wall; and a first catalyst layer that includes a metal catalyst and is disposed within the dividing wall so as to be in contact with the exit side cell and not in contact with the entry side cell, and no catalyst layer is provided in the region in contact with the entry side cell.

Abstract: An exhaust gas purifying catalyst includes: a wall-flow structure substrate including an inlet cell, an outlet cell, and a porous partition; a first catalyst layer formed inside the partition such that a thickness of the first catalyst layer is between 40% and 60%, inclusive, of an overall thickness Tw of the partition; and a second catalyst layer formed inside the partition such that the second catalyst layer extends across an entire region of the partition in a thickness direction thereof.
