Abstract
A catalystprovided for a filter body for combusting PM contains activated aluminasand, active-oxygen-release materialsand, catalytic metal, and alkali earth metal. The alkali earth metalis loaded on each of the activated aluminasand, and the active-oxygen-release materialsand. A percentage by mass of the alkali earth metal, loaded on the active-oxygen-release materialsand, to the active-oxygen-release material is smaller than a percentage by mass of the alkali earth metal, loaded on the activated aluminasand, to the activated alumina.
