The present invention is a flame retardant polycarbonate resin composition comprising 100 parts by weight of a polycarbonate resin (A), 0.01 to 3 parts by weight of a silicone compound (B) having a branched chain structure and organic functional groups, wherein said organic functional groups comprise (i) aromatic groups or (ii) aromatic groups and hydrocarbon groups (excluding aromatic groups), 0.5 to 20 parts by weight of a phosphazene compound (C), 0.01 to 2 parts by weight of an organometallic salt (D) and 0.01 to 2 parts by weight of a fiber-forming type fluorine-containing polymer (E). 5 to 25 parts by weight of titanium oxide (F) and 0.05 to 2 parts by weight of a poly(organo hydrogen siloxane) (G), per 100 parts by weight of a polycarbonate resin (A), may be further added. <??>Since the flame retardant polycarbonate resin composition of the present invention does not contain a halogen type flame retarding agent comprising chlorine compounds, bromine compounds and the like, no gas derived from a halogen type flame retarding agent are generated when burned. Furthermore, the composition has a high degree of flame retardance, a light reflectivity, and an excellent impact resistance, a heat resistance, a light resistance and can be used for various internal and external uses associated with electrical, electronic and OA applications.
