Abstract
To improve a CO conversion in stoichiometry-lean atmosphere, and additionally to prevent the rise of pressure loss. A catalytic coating layeris constituted of a lower layerincluding an oxygen storage capacity material and an upper layerbeing formed on a surface of the lower layerand including a catalytic noble metal, and a thickness of the upper layer is adapted so as to be 5 μm-40 μm. The upper layeris good in terms of gas diffusibility, and thereby OSC resulting from the oxygen storage capacity material being included in the lower layeris demonstrated maximally.
