Abstract Provided is a polycarbonate-based resin composition including: 50%-99% by mass of a polycarbonate resin (S) including a polycarbonate-polyorganosiloxane copolymer (A) and an aromatic polycarbonate resin (B) other than the polycarbonate-polyorganosiloxane copolymer (A), said polycarbonate-polyorganosiloxane copolymer (A) including a polycarbonate block (A-1) comprising a specified repeating unit and a polyorganosiloxane block (A-2) including a specified repeating unit; and 1%-50% by mass of a polyester resin (C). The polycarbonate resin composition is characterized by the average chain length of the polyorganosiloxane block (A-2) being 50-500. L'invention concerne une composition de résine à base de polycarbonate comprenant : 50 % à 99 % en masse d'une résine de polycarbonate (S) comprenant un copolymère de polycarbonate-polyorganosiloxane (A) et une résine de polycarbonate aromatique (B) autre que le copolymère de polycarbonate-polyorganosiloxane (A), ledit copolymère de polycarbonate-polyorganosiloxane (A) comprenant un bloc polycarbonate (A-1) comprenant un motif récurrent spécifié et un bloc de polyorganosiloxane (A-2) comprenant un motif récurrent spécifié ; et 1 % à 50 % en masse d'une résine de polyester (C). La composition de résine de polycarbonate est caractérisée par la longueur de chaîne moyenne du bloc de polyorganosiloxane (A-2) de 50 à 500. 特定の繰り返し単位からなるポリカーボネートブロック(A-1)及び特定の繰り返し単位を含むポリオルガノシロキサンブロック(A-2)を含むポリカーボネート-ポリオルガノシロキサン共重合体(A)、並びに前記ポリカーボネート-ポリオルガノシロキサン共重合体(A)以外の芳香族ポリカーボネート系樹脂(B)を含むポリカーボネート系樹脂(S)50質量%以上99質量%以下と、ポリエステル系樹脂(C)とを1質量%以上50質量%以下含み、前記ポリオルガノシロキサンブロック(A-2)の平均鎖長が50以上500以下であることを特徴とする、ポリカーボネート系樹脂組成物を提供する。
