Zusammenfassung:	To provide a methacrolein production catalyst enabling methacrolein to be produced in good yield.SOLUTION: A methacrolein production catalyst is provided which includes a heteropolyacid having a composition represented by the following formula (I), and is for use in production of methacrolein by an oxidative dehydrogenation reaction of isobutyraldehyde. PaMobXcYdOe (I). (In formula (I), each of P, Mo and O represents phosphorus, molybdenum and oxygen. X represents at least one selected from transition metal elements. Y represents at least one selected from alkali metal elements and ammonium cations. a to e represent the molar ratio of respective component, and when b=12, 1
