Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a nonhalogen type flame-retardant resin composition which has good processability and can give molding having good appearance and mechanical properties by mixing a polyester resin with a specified phosphoric ester, a novolac phenol resin and glass fibers. SOLUTION: This composition comprises 100 pts.wt. polyester resin, 5-50 pts.wt. phosphoric ester represented by the formula (wherein X is a valance bond or C(CH3 )2 ; and (n) is 0 or 1), 3-40 pts.wt. novolac phenol resin and 0-50 pts.wt. glass fibers. The polyester is desirably polybutylene terephthalate or a polyester elastomer comprising polybutylene terephthalate and polyoxytetramethylene glycol.
