Abstract: Particles for an exhaust gas purification catalyst including: inorganic oxide particles; and an inorganic coating layer covering the inorganic oxide particles. The particles for an exhaust gas purification catalyst have reduced cumulative pore volume in a pore diameter range of 0.1-20 ?m compared to a cumulative pore volume in a pore diameter range of 0.1-20 ?m of inorganic oxide particles before being coated with the inorganic coating layer. Accordingly, the particles for an exhaust gas purification catalyst have a higher thermal conductivity than the inorganic oxide particles before being coated with the inorganic coating layer.
