PROBLEM TO BE SOLVED: To provide a method for producing a 1,3-diiodohydantoin compound, by which the 1,3-diiodohydantoin compound can efficiently be produced in the simple process in a high yield under mild conditions and under simple post- treatments such as a simple purification treatment and a simple waste liquid treatment. SOLUTION: This method for producing the 1, 3-diiodohydantoin compound represented by formula (I) (R1 and R2 are each H or a 1-6C alkyl) is characterized by reacting a hydantoin compound represented by formula (II) with iodine monochloride in the presence of a base in water solvent.
