PURPOSE: A polycarbonate-based thermoplastic resin composition is provided which does not generate silver in the exterior and has excellent heat resistance and flame retardancy. CONSTITUTION: A polycarbonate-based thermoplastic resin composition comprises (A) 45 - 95 % by weight of a thermoplastic polycarbonate resin containing no halogen, (B) 5 - 50 % by weight of a grafted copolymer resin having a rubber-modified styrene containing no halogen, (C) 0 - 30 % by weight of a copolymer resin having styrene containing no halogen, (D) a phosphate ester compound, (E) magnesium hydroxide, and (F) a fluorinated polyolefin-based resin, wherein, with respect to 100 % by weight of (A) + (B) + (C), (D) + (E) is 2 - 20 % by weight and (F) is 0 - 2 % by weight, and in (D) + (E), the ratio of (D) to (E) ranges from 50 : 50 to 90 : 10. |
