A graft copolymer capable of providing impact resistance, flame retardance, and color rendering properties to a thermoplastic resin is described. The graft copolymer contains a polyorganosiloxane, and is obtained by graft-polymerizing vinyl monomers including a (meth)acrylate ester (b
1
) having an alkyl group or an aromatic group and an aromatic vinyl monomer (b
2
) on a polyorganosiloxane-based rubber. The graft copolymer has a volume average particle diameter of 200-2000 nm, and contains 0.1-69 mass % of polyorganosiloxane. A thermoplastic resin composition is also described, containing a thermoplastic resin (A), the graft copolymer, a fluorine resin (C) and a flame retardant (D). A molded article is also described, which is obtained by molding the thermoplastic resin composition.
