Exhaust gas purifying catalyst

An exhaust gas-purifying catalyst that is disposed in an exhaust pipe for an internal combustion engine and purifies exhaust gases discharged from the internal combustion engine, comprising:

• oxide particles each having interdispersed therein A crystallites that are loaded with a noble metal and B crystallites that are not loaded with a noble metal,
• wherein:
• the A crystallites loaded with a noble metal are composed of an oxide containing at least one of zirconium (Zr) and cerium (Ce),
• the B crystallites not loaded with a noble metal are composed of a cerium (Ce)-containing oxide having a higher Ce content (mol %) than the oxide making up the A crystallites,
• the oxide particles have a specific surface area after 5 hours of heat treatment at 1,150° C. in open air of 30 m2/g or more, and
• the A crystallites and the B crystallites are present within each of the oxide particles in a highly interdispersed manner such that, as observed by electron microscopy, ten or more crystallites of the same type are nowhere mutually contiguous.
