PROBLEM TO BE SOLVED: To provide a method for producing a molybdenum carrying sponge metal catalyst which is costwise advantageous and suppresses damage to the environment to the minimum. SOLUTION: In the method for producing a molybdenum carrying sponge metal catalyst by bringing an aqueous solution containing molybdic acid and/or a molybdate into contact with a sponge metal catalyst, water containing an alkaline earth metal salt and/or an alkaline earth metal chloride is brought into contact with the sponge metal catalyst and then the aqueous solution containing the molybdic acid and/or the molybdate is brought into contact with the sponge metal catalyst at pH 4-12.
