PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition which is improved in flame retardancy while maintaining transparency, and to provide a molded article of the polycarbonate resin composition. SOLUTION: The transparent flame-retardant polycarbonate resin composition includes (A) a polycarbonate resin component comprising (A-1) 10 to 90 mass% of an aromatic polycarbonate resin produced by using a dihydroxybiphenyl as a part of a divalent phenol component, (A-2) 10 to 90 mass% of an aromatic polycarbonate-polyorganosiloxane copolymer, and (A-3) 0 to 80 mass% of an aromatic polycarbonate resin which is different from the components (A-1) and (A-2), wherein the component (A) preferably contains a polyorganosiloxane at a ratio of 0.3 to 1.6 mass% and may additionally contain (B) an organic metal salt in an amount of 0.01 to 1 pts.mass based on 100 pts.mass of the component (A). As the organic metal salt, at least one is selected from a sulfonic acid alkali metal salt, a sulfonic acid alkaline earth metal salt, a polystyrenesulfonic acid alkali metal salt, and a polystyrenesulfonic acid alkaline earth metal salt.
