【Task】 In a method for producing a corresponding aliphatic dicarboxylic acid by subjecting a cycloalkanone compound to liquid phase oxidation with molecular oxygen, the corresponding aliphatic dicarboxylic acid can be handled more safely, and in high yield, producing the corresponding aliphatic dicarboxylic acid. It seeks to provide a way. [Solution] The problem can be solved by liquid-phase oxidation of a cycloalkanone compound with molecular oxygen in the state where a cerium compound and a cobalt compound coexist as a catalyst. Preferably, the cycloalkanone compound is cyclohexanone and cyclododecanone, and it is preferably solved by a catalyst system in which at least one of the catalyst components selected from a cerium compound and a cobalt compound is a nitrate.
