Abstract
An inside layer including zeolite and an outside layer including alumina and Pd are formed in a layered shape on a carrier, and Ag and Bi are simultaneously allowed to be carried on the inside and outside layers through impregnation. Thus, production of an alloy through a reaction between Pd and Ag can be suppressed by Bi.
