| description | Provided are a catalyst that may suppress the production of a coke-like substance in a reaction for producing a conjugated diolefin from a mixed gas including a monoolefin having 4 or more carbon atoms and molecular oxygen, by catalytic oxidative dehydrogenation; and a method for producing the catalyst. A composite metal oxide catalyst for producing a conjugated diolefin from a mixed gas including a monoolefin having 4 or more carbon atoms and molecular oxygen by a catalytic oxidative dehydrogenation reaction, the composite metal oxide catalyst having a relative intensity range of X-ray diffraction peaks represented by the following Formula (A): 0 ¤ Rh (= Ph1/Ph2) < 0.8 (A) wherein Ph1 represents the maximum peak height within the range of 2¸ = 28.1° ± 0.2° for the X-ray diffraction peaks; Ph2 represents the maximum peak height within the range of 2¸ = 27.9° ± 0.2° for the X-ray diffraction peaks; and Rh represents the relative intensity ratio of Ph1 with respect to Ph2. |
