摘要：
A high exhaust gas-purifying efficiency is achieved. An exhaust gas-purifying catalyst includes a substrate, an oxygen storage layer covering the substrate and including an oxygen storage material, and a catalytic layer covering the oxygen storage layer and including palladium, rhodium and a carrier supporting them, the catalytic layer having a precious metal concentration higher than that of the oxygen storage layer.
