Abstract
An exhaust gas purifying catalyst includes an inlet-side catalyst layer formed on an inner side of the partition wall from a surface of the partition wall in contact with an inlet-side cell and formed along an extension direction from an end portion on the exhaust gas inflow side, and an outlet-side catalyst layer formed on the inner side of the partition wall from a surface of the partition wall in contact with an outlet-side cell and formed along the extension direction from an end portion on the exhaust gas outflow side. Here, a sum of the lengths of the inlet-side catalyst layer and the outlet-side catalyst layer is larger than the entire length of the partition wall, and a total amount of an SCR catalyst body present in the outlet-side catalyst layer is larger than a total amount of an SCR catalyst body present in the inlet-side catalyst layer.
