摘要：
A composite oxide catalyst includes Ce that is a first metal, La that is a second metal, and a third metal as contained metals. The third metal is a transition metal, or a rare-earth metal other than Ce and La. A Ce content in the contained metals is higher than or equal to 5 mol % and lower than or equal to 95 mol %. An La content in the contained metals is higher than or equal to 2 mol % and lower than or equal to 93 mol %. A content of the third metal in the contained metals is higher than or equal to 2 mol % and lower than or equal to 93 mol %.
