[Problem] To provide a polycarbonate resin composition capable of obtaining a molded article having excellent fluidity, flame retardancy and chemical resistance and having high impact strength. A polycarbonate resin (A) containing a polycarbonate-polyorganosiloxane copolymer (A-1) having a specific structure, a structural unit derived from acrylonitrile and styrene, and a structural unit derived from methyl methacrylate. The content of the polyorganosiloxane block portion in the total resin composition is 0. 0, including a copolymer (B) that does not have, and a copolymer (C) having a structural unit derived from butadiene and methyl methacrylate. 1 to 10% by mass, and the total content of the structural units derived from the acrylonitrile in the total resin composition and the structural units derived from the styrene in the total resin composition is 8 to 45% by mass, Content of the structural unit derived from the said butadiene in all the resin compositions is 3-10 mass%, and the viscosity average molecular weight of said (A) ( v) is a polycarbonate resin composition which is 20,000～25,000.
