Abstract
This exhaust gas purifying catalyst is provided with a substrateand a catalyst layerformed on a surface of the substrate. The catalyst layercontains zeolite particlesthat support a metal, and a rare earth element-containing compoundthat contains a rare earth element. The rare earth element-containing compoundis added in such an amount that the molar ratio of the rare earth element relative to Si contained in the zeoliteis 0.001 to 0.014 in terms of oxides.
