Abstract: An exhaust gas purification catalyst includes a catalytic layer constituted by a heap of particles each obtained by applying a thin film of an oxygen storage material containing ceria to the surface of a base made of a material having a high-specific surface area, and allowing a precious metal to be supported on the surface of the thin film of the oxygen storage material.
