To provide a polycarbonate resin composition which is excellent in flame retardance, melt fluidity, impact resistance, color tone and a low mold deposit property, even when the molding temperature is high and the composition is exposed in an environment of a high temperature and humidity for a long time.

This polycarbonate flame-retardant resin composition is composed of (A) an aromatic polycarbonate resin of 50-98 wt. parts, (B) a copolymer such as SAN, BAAS, etc., of 0-49 wt. parts, (C) a graft copolymer containing a cyanides group of 0.5-30 wt. parts, (D) a graft copolymer containing a (metha) acrylate of 0.5-30 wt. parts, (E) at least one of organic phosphorus compound oligomers having an acid value of 1 mgKOH/g or less of 0.1-30 wt. parts, and (F) at least one of epoxy compounds of 0.01-1 wt. parts.
