PROBLEM TO BE SOLVED: To provide a flame-retardant polycarbonate resin composition excellent in heat stability at the time of molding and use, and capable of being stably molded without generating yellowing and silver marks, especially when injection- molded using a hot-runner mold, by making the composition flame-retardant with a phosphoric ester compound. SOLUTION: This flame-retardant polycarbonate resin composition is obtained by melting and kneading 1-30 pts.wt. (C) of a phosphate ester compound having an acid value of <=1 mgKOH/g in 100 pts.wt. of a resin comprising (A) a polycarbonate resin in an amount of 60-100 wt.% and (B) a styrene-based resin in an amount of 40-0 wt.%. The monomer content of the phosphoric ester compound is preferably <=3 wt.%. |
