When maleimide (manufactured by Aldrich Chemical Co., Inc.) of 24 parts, 35% HCOH (manufactured by Wako Pure Chemical Industries, Ltd.) of 21 parts, and an aqueous 5% NaOH solution of 0.7 parts are mixed and reacted at 40° C. for 2 hours to precipitate hydroxymethylmaleimide in the form of a white crystal. The produced hydroxymethylmaleimide is filtered in reduced pressure and vacuum dried at room temperature. The crude crystal of hydroxymethylmaleimide obtained in such a manner is recrystallized in ethyl acetate to obtain hydroxymethylmaleimide of 22 parts.
