PROBLEM TO BE SOLVED: To provide a resin composition suitable as a material for profile extrusion molding. SOLUTION: The thermoplastic resin comprises (A) a graft copolymer obtained by grafting (G) a (meth)acrylate-based rubber-like polymer with a polymer having a vinyl-based monomer unit and (B) a polymer having (meth) acrylate unit and further comprises (C) a copolymer having 50-95 mass% methyl methacrylate unit and 5-50 mass% acrylic acid alkyl ester unit in which carbon number of the alkyl group is 1-10 and (D) a copolymer having 40-90 mass% methacrylic acid alkyl ester unit in which carbon number of the alkyl group is 1-18 and 60-10 mass% acrylic acid alkyl ester unit in which carbon number of the alkyl group is 1-18 and having 100,000-500,000 mass-average molecular weight and containing 10-50 mass% component having≤50,000 mass molecular weight in amounts of the component C of 0.1-5 pts.mass and the component D of 0.01-20 pts.mass based on 100 pts.mass total amount of the components A and B.
