A flame-retardant resin composition which comprises: a base resin (A); a flame retardant (B) comprising at least one aromatic resin (B1) selected among polyphenylene oxide resins and polyphenylene sulfide resins, a phosphoric ester (B2), and a nitrogenous cyclic compound (B3); and a styrene resin (C) having a melt flow rate of 8 g/10 min or lower. The base resin may be a polyester resin. The styrene resin (C) may be one having a melt flow rate of 0.1 to 5 g/10 min. The phosphoric ester (B2) may be a fused phosphoric ester, and the nitrogenous cyclic compound (B3) may be a polyphosphoric acid salt of an aminated triazine compound, a polyphosphoramide, etc. The flame-retardant resin composition has been flameproofed without using any halogenated flame retardant. |
