摘要： PROBLEM TO BE SOLVED: To provide a catalyst for cleaning exhaust gas, in which the amount of a noble metal to be used is reduced and which can exhibit more excellent performance of cleaning the exhaust gas.SOLUTION: A first cleaning member 2 containing a 3d transition element and no noble metal and second cleaning members 3, which are disposed respectively and adjacently to the first cleaning member 2 on both sides being the upstream and the downstream sides of the first cleaning member 2 in the passing direction of the exhaust gas and each of which contains the noble metal, are incorporated in the catalyst 1 for cleaning exhaust gas. Since the noble metal-containing second cleaning members 3 are disposed respectively and adjacently to the first cleaning member 2, which contains the 3d transition element and no noble metal, on both sides being the upstream and the downstream sides of the first cleaning member 2 in the passing direction of the exhaust gas, the catalyst 1 for cleaning exhaust gas can efficiently clean the exhaust gas and can allow the amount of the noble metal to be used therein to be reduced.
