The invention provides a thermoplastic resin composition, which does not substantially compromise color rendering and flame retardance of a thermoplastic resin and has high impact resistance, slidability, and chemical resistance in a wide scope of environmental conditions ranging from low temperature to high temperature. A graft copolymer (GF2) containing rubber is a graft copolymer containing rubber formed by performing graft polymerization of 1 or more vinyl monomers on a composite rubber containing a polyorganosiloxane (B1) and a polyalkyl (meth)acrylate (B2). The content of a component derived from a silane compound containing a vinyl-based polymerizable group in the polyorganosiloxane (B1) is 1 mass % to 10 mass %. The volume-average particle size of the graft copolymer containing rubber is 300 nm to 2000 nm. The content of the polyorganosiloxane (B1) in the graft copolymer containing rubber is 70 mass % to 98 mass %. An acetone soluble matter is 5.0 mass % or more and 30.0 mass % or less.
