An exhaust gas purifying catalyst comprises a powder including a porous material having a specific surface area of 150 m2/g or more, cerium and platinum. Cerium and Platinum are loaded on the porous material. The powder has platinum dispersion of 70% or more before baking and platinum dispersion of 50% or more after baking in air at 700° C. Additionally, a reduction rate R of the platinum dispersion after the baking against the platinum dispersion before the baking is below 40%. The reduction rate R is represented by a following equation (1): R=(1−(Pt dispersion after baking)/(Pt dispersion before baking))×100  (1).
