Disclosed is a thermoplastic resin composition having high impact resistance without decreasing weather resistance even when only a small amount of an impact strength modifier is blended therein. The thermoplastic resin composition contains 100 parts by weight of a thermoplastic resin (A) and 0.5-20 parts by weight of a graft copolymer (B). The thermoplastic resin composition is characterized in that the graft copolymer (B) contains 70-99% by weight of a crosslinked core (b2), which is obtained by polymerizing a monomer for core (b2) containing not less than 70% by weight of an acrylate in the presence of 0.5-20% by weight of a non-crosslinked seed (b1) having a weight average molecular weight of not more than 40,000, and 0.5-10% by weight of a shell (b3), which is obtained by polymerizing a monomer for shell (b3) containing not less than 50% by weight of a methacrylate. This thermoplastic resin composition is further characterized by containing 0.01-3.0 parts by weight of a water-soluble polymer compound (C) having a physical gel-forming property per 100 parts by weight of the graft copolymer (B).
