An exhaust gas purifying catalyst includes a base material and a catalyst layer. A first catalyst region including the catalyst layer formed therein is provided on an entry side surface of a partition wall of the base material. A second catalyst region including the catalyst layer formed on a wall surface of a pore is provided in a prescribed region from an exit side surface of the partition wall toward an entry side cell. A catalyst unformed region in which a catalyst layer is substantially not formed is provided between the first and second catalyst regions in the thickness direction Y of the partition wall. Thus, it is possible to prevent the deposition of PMs in the second catalyst region including the catalyst layer formed in the pore, and to establish the compatibility between the noxious gas purifying performance and the pressure loss suppressing performance at a high level.
