Zusammenfassung:	PURPOSE:To obtain a flame retardant which is added to a synthetic resin to give it excellent flame retardancy, heat resistance, weathering resistance, electrical properties, water resistance, etc., by reacting a digycidyl ether compound with a dihydroxy compound. CONSTITUTION:A flame retardant for synthetic resin, which is a product obtained by reacting 1mol of a diglycidyl ether compound (a) with 0.5-1.0mol of a dihydroxy compound (b) and has a halogen content >=10wt%, preferably, >=40wt%. Said diglycidyl ether compound (a) comprises a compound of formula I, which may be used in combination with the compound of formula II. When the compound of formula II is used, it is preferable that compound (a) contains at least 10wt% compound of formula I. In the formulas, X is a halogen, p and q are each 0-2, R1 is a 1-4C alkylidene or the like, m and n are each 1-5, r and s are each 0-2, and R3 is a 1-4C alkylidene or the like.
