Summary:To provide a laminated catalyst with enhanced durability.SOLUTION: A laminated catalyst according to an embodiment has an oxide layer, a first catalyst layer on the oxide layer, and a second catalyst layer on the first catalyst layer. The oxide layer includes a non-noble metal as the main component. The first catalyst layer includes an oxide of noble metal including Ir and/or Ru as the main component. The second catalyst layer includes an oxide of noble metal including Ir and/or Ru as the main component. The first catalyst layer is denser than the second catalyst layer.SELECTED DRAWING: Figure 1 【課題】実施形態は、耐久性に優れた積層触媒を提供する。【解決手段】 実施形態の積層触媒は、酸化物層と、酸化物層上に第１触媒層と、第１触媒層上に第２触媒層と、を有し、酸化物層は、非貴金属を主体とする酸化物層であり、第１触媒層は、Ｉｒ及びＲｕを主成分とする貴金属の酸化物を含み、第２触媒層は、Ｉｒ及びＲｕを主成分とする貴金属の酸化物を含み、第１触媒層は、第２触媒層よりも緻密である。【選択図】 図１
