Abstract
An exhaust gas-purifying catalyst material includes first oxide particles having an average particle diameter Dof 1 μm to 95 μm and having an oxygen storage capacity, second oxide particles having an average particle diameter Dof 0.05 μm to 0.5 μm, containing a metal element, and having no oxygen storage capacity, precious metal particles, and acidic oxide particles. The material has a correlation coefficient ρ of 0.45 or more obtained using first characteristic X-ray intensity for the metal element contained in the second oxide particle, second characteristic X-ray intensity for an element other than oxygen contained in the acidic oxide particle, and third characteristic X-ray intensity for a precious metal element contained in the precious metal particle.
