PROBLEM TO BE SOLVED: To obtain a polycarbonate resin composition having high impact strength and excellent flame-retardancy and heatstability and useful for electric and electronic parts, etc., by compounding a polycarbonate resin with a prescribed amounts of specific multi-layer structure polymer, etc. SOLUTION: This polycarbonate resin composition is produced by compounding (A) 100 pts.wt. of an aromatic polycarbonate resin having a viscosity-average molecular weight of 14,000-30,000 with (B) 0.01-5 pts.wt. of a sulfonic acid metal salt such as an aromatic sulfone sulfonic acid metal salt or a perfluoroalkane-sulfonic acid metal salt and (C) 0.5-30 pts.wt. of a multi- layer structure polymer having an inner core composed of a diene rubber polymer such as butadiene rubber polymer and an outermost shell composed of a vinyl copolymer such as an alkyl (meth)acrylate polymer. The average wall thickness of the molded article composed of the flame-retardant polycarbonate resin composition is preferably 0.1-2.0 mm. |
