Provided are a graft copolymer which has good moldability and good continuous moldability and with which a thermoplastic resin molded article having excellent impact resistance can be produced, a method for producing the graft copolymer, and a thermoplastic resin composition including the graft copolymer. A graft copolymer (B-I) produced by grafting at least one vinyl monomer (b-I) selected from the group consisting of an aromatic vinyl, an alkyl (meth)acrylate, and a vinyl cyanide to a rubbery polymer mixture including a rubbery polymer (A-I) and a hydrophobic substance, the rubbery polymer (A-I) including an alkyl (meth)acrylate unit and a multifunctional monomer unit copolymerizable with the alkyl (meth)acrylate, the hydrophobic substance having a kinematic viscosity of 5 mm2/s or more at 40°C or a kinematic viscosity of 2 to 4 mm2/s at 100°C, a principal constituent of the hydrophobic substance being a hydrocarbon. A thermoplastic resin composition including the graft copolymer (B-I). A molded article produced using the thermoplastic resin composition.
