Even under low-temperature conditions such as when the engine is started and provides an exhaust gas purifying catalyst to improve the carbon monoxide purification performance for the exhaust gas. The exhaust gas purifying catalyst of the present invention, the base material 10 has the adsorption layer 30 is disposed on the oxidation catalyst 20 and the oxidation catalyst are disposed on the substrate. Here, the oxidation catalyst has the noble metal that is supported on the carrier particles and the carrier particles, also the loading density of the noble metal in the oxidation catalyst layer is greater than the loading density of the noble metal in the adsorption layer. In addition, the absorption layer has a hydrocarbon adsorbent particles, and the content of the hydrocarbon adsorbent particles in the adsorption layer is larger than the content of the hydrocarbon adsorbent particles in the oxidation catalyst layer.
