Abstract
The present invention provides an exhaust gas purification catalyst including a base materialand a catalyst layerprovided on the base material. The catalyst layerincludes: a catalyst metal; and a carrying materialcarrying the catalyst metal. The carrying materialincludes: an OSC materialhaving an oxygen storage capacity; and a carrierother than the OSC material. The OSC materialhas a mean particle diameter Dx of 1.5 μm or more which is larger than the mean particle diameter Dy of the carrierother than the OSC material
