PURPOSE: A polycarbonate resin composition is provided to have excellent flame retardance, thermal resistance, thermal stability, mechanical strength, impact resistance, and dimensional stability. CONSTITUTION: A polycarbonate resin composition comprises 100.0 parts by weight of base resin, 1-20 parts by weight of phosphorous-based flame retardant, 0.1-20 parts by weight of inorganic filler, and 0.1-5 parts by weight of metal salt flame retardant. The base resin comprise 40-98 weight% of polycarbonate resin, 1-30 parts by weight styrene based copolymer, and 1-30 parts by weight of rubber-styrene graft copolymer. The amount of branched polycarbonate resin in whole polycarbonate resin is 10-50 weight%. The average diameter of the inorganic filler is 1-10 micron.
