Abstract

Provided is a polycarbonate resin composition, including: a polycarbonate resin (A) containing a polycarbonate-polyorganosiloxane copolymer (A-1) having a specific structure; a copolymer (B) having constituent units derived from acrylonitrile and styrene, and being free of a constituent unit derived from methyl methacrylate; and a copolymer (C) having constituent units derived from butadiene and methyl methacrylate, in which: a content of the polyorganosiloxane block moiety in the entire resin composition is from 0.1 mass % to 10 mass %; a total of a content of the constituent unit derived from the acrylonitrile in the entire resin composition and a content of the constituent unit derived from the styrene in the entire resin composition is from 8 mass % to 45 mass %; a content of the constituent unit derived from the butadiene in the entire resin composition is from 3 mass % to 10 mass %; and the (A) has a viscosity-average molecular weight (Mv) of from 20,000 to 25,000.
