PROBLEM TO BE SOLVED: To provide a flame-retardant polycarbonate resin composition being excellent in wet-heat resistance and excellent also in heat stability, processability, transparency, etc., and having flame retardancy improved without using any chlorine- or bromine-containing compound. SOLUTION: The flame-retardant polycarbonate resin composition is prepared by formulating 100 pts. wt. polycarbonate containing 100 to 20 wt.% aromatic polycarbonate resin having a structural viscosity index N of 1.2 or higher with 0.001 to 5 pts. wt. flame retardant represented by formula (B-1) or formula (B-2). In formula (B-1), m is an integer of 1 to 12; and M is an alkali metal or an alkaline earth metal; q is 2 when M is an alkali metal and is 1 when M is an alkaline earth metal. In formula (B-2), Rf is an optionally substituted perfluoroalkyl group having 2 to 12 carbon atoms in total; M' is an alkali metal or an alkaline earth metal; and n is equal to the valence of M'.
