Abstract: Provided is an exhaust gas purification catalyst providing a catalyst performance and an OSC performance at the same time even at low temperature. The present disclosure relates to an exhaust gas purification catalyst including a substrate and a catalyst coating layer coated on the substrate. The catalyst coating layer includes a first catalyst coating layer containing Pd and/or Pt and a second catalyst coating layer containing Rh. The first catalyst coating layer is formed from an end portion in an upstream side with respect to an exhaust gas flow direction in the exhaust gas purification catalyst. The second catalyst coating layer includes an upstream coating layer and a downstream coating layer. Rh in the upstream coating layer and the downstream coating layer are supported on specific carrier particles. Further, a particle diameter of Rh is controlled.
