An object is to provide a novel organophosphorus compound which can impart flame retardancy to an amorphous resin in a smaller addition amount without deteriorating heat resistance and transparency, and also can be applied to a wide range of resins, a flame retardant containing the same, and a method for producing an organophosphorus compound. An organophosphorus compound represented by the following general formula (1) (wherein R1 and R2 are independently hydrogen, an alkyl group having 1 to 15 carbon atoms, an aryl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 15 carbon atoms, or an alkylaryl group having 7 to 15 carbon atoms, R3 and R4 are independently an alkyl group having 1 to 15 carbon atoms, an aryl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 15 carbon atoms, an alkylaryl group having 7 to 15 carbon atoms, an alkoxy group having 1 to 15 carbon atoms, an aryloxy group having 6 to 12 carbon atoms, an aralkyloxy group having 7 to 15 carbon atoms, or an alkylaryloxy group having 7 to 15 carbon atoms, provided that R3 and R4 may be bound to each other to form a ring, and m and n are independently 1, 2, 3 or 4), a flame retardant containing the same, and a method for producing an organophosphorus compound.
