Summary:PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition excellent in having well balanced properties such as flame resistance, transparency, hue and thermal stability. SOLUTION: The flame-retardant aromatic polycarbonate is produced by adding 0.001 to 0.5 pt.wt. of a halogen-free aromatic metal sulfonate compound represented by general formula (1) (wherein R1is a H atom or a 1-10C alkyl, R2is a H atom or a 1-7C alkyl, a 6-20C aralkyl or a 5-15C aryl, and M is Rb, Cs or Fr) to 100 pts.wt. of the aromatic polycarbonate resin.
