Provided is a thermoplastic resin composition having an excellent balance among physical properties including impact resistance, fluidability and heat resistance. A thermoplastic resin composition comprising: 10 to 95 parts by weight of a polycarbonate resin (A); 5 to 90 parts by weight of a graft copolymer (B) as mentioned below; and 0 to 50 parts by weight of a copolymer (C) as mentioned below. The graft copolymer (B): a graft copolymer which is produced by the graft polymerization of 10 to 80 parts by weight of a rubbery polymer with 20 to 90 parts by weight of a monomer component comprising an aromatic vinyl monomer and/or a cyanide vinyl monomer, wherein the rubbery polymer has a weight average particle size of 150 to 450 nm and also has a 10 wt% particle size of 50 to 250 nm and a 90 wt% particle size of 450 to 650 nm in a particle size cumulative weight fraction. The copolymer (C): a copolymer which is produced by copolymerizing an aromatic vinyl monomer, a cyanide vinyl monomer and another vinyl monomer with one another. |
