Abstract
An exhaust gas purifying catalyst comprises: a plurality of catalyst units which contain anchor particles that support noble metal particles; and an enclosure material that internally contains the plurality of catalyst units and separates the catalyst units from each other. Both the anchor particles and the enclosure material contain an alkali element and/or an alkaline earth element. Due to this configuration, this exhaust gas purifying catalyst is capable of maintaining the exhaust gas purification performance by suppressing agglomeration of the noble metal particles even in cases where the ambient temperature is high.
