The polycarbonate resin composition of the present invention comprises (A) 100 parts by mass of an end-modified polycarbonate resin terminated with a (C10-C35 alkyl)phenoxy group or a polycarbonate resin mixture comprising the end-modified polycarbonate resin and another polycarbonate resin; (B) 0.1 to 10 parts by mass of a functionalized silicone compound; and (C) 0.2 to 10 parts by mass of a core-shell type rubber-like graft elastomer. Another polycarbonate resin composition of the present invention comprises a resin mixture comprising 100 parts by mass of a resin mixture comprising (A') 1 to 99% by mass of an end-modified polycarbonate resin terminated with a (C10-C35 alkyl)phenoxy group or a polycarbonate mixture comprising the end-modified polycarbonate resin and another polycarbonate resin and (B') 99 to 1% by mass of a styrene resin; and (C') 0.01 to 5 parts by mass of a polyfluoroolefin resin. By the combined use of the polycarbonate having a specific terminal structure with the functionalized silicone compound and the core-shell type rubber-like graft elastomer, or with the styrene resin and the polyfluoroolefin resin, the moldability/extrudability, i.e., melt fluidity, of the polycarbonate composition is improved while retaining the good impact resistance inherent to polycarbonate resin, thereby enabling the production of thin-wall shaped articles. The polycarbonate resin composition of the present invention is also improved in the flame retardancy without using a halogen- or phosphorus-containing flame retardant, and is therefore excellent in the heat resistance and the recyclability.
