Abstract: The exhaust gas purifying catalyst disclosed here includes a substrate 10 and a catalyst coat layer 30 formed on the surface of the substrate 10. The catalyst coat layer 30 is formed in a laminate structure having two layers, with a first layer 34 being nearer to the surface of the substrate 10 and a second layer 32 being relatively further from this surface. The second layer 32 includes a carrier and a noble metal supported on the carrier. The first layer 34 is a noble metal-free layer that does not contain a noble metal but does contain an OSC material having oxygen storage capacity.
