摘要： A Cr trapping agent is disposed so that it contacts with constituting components of the substrate containing Cr. As the Cr trapping agent, an element or Ag is used, wherein the element is stronger in basicity than alkali metals or alkaline earth metals. Since the Cr trapping agent prevents transfer of Cr towards the alkali metals or alkaline earth metals, the reaction between Cr and alkali metals or alkaline earth metals is prevented.

摘要： Use of a metallic material containing chromium as a substrate of an exhaust gas purifying catalyst has a problem that the chromium contained in the substrate migrates to a catalytically active component and reacts with the catalytically active component to reduce exhaust gas purification performance. Thus, a film which inhibits the chromium contained in the substrate from migrating is arranged on the substrate's surface. The film is desirably formed by oxidizing a substrate in the air. It is also desirable that a substrate containing aluminum therein be oxidized to cause aluminum contained in the substrate to separate out and thereby form an alpha-alumina film. The film is preferably such that, when the exhaust gas purifying catalyst is heated at 850° C. in the air for 300 hours, the amount of chromium migrated to the catalytically active component is controlled to 0.5 percent by weight or less based on the catalytically active component.
