PROBLEM TO BE SOLVED: To provide an organophosphorus compound having a high flame-retardant effect, a flame retardant based thereon, and a flame-retardant organic polymer compound and to make it possible to keep the heat resistance of a flame-retardant polymer composition and to alleviate the defect, i.e., hydrolyzability, of the flame retardant. SOLUTION: Provided are a novel organophosphorus compound represented by structural formula 1 (wherein R<SP>1</SP>is a methyl group); a flame retardant based on the compound; and a flame-retardant organic polymer composition containing the flame retardant.
