PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition which excels in flowability and furthermore excels in the impact resistance, chemical resistance, and heat resistance of obtained molded articles. SOLUTION: The thermoplastic resin composition comprises a polyamide (A), a graft copolymer (B) prepared by graft polymerizing a monomer component (b-2) onto a rubbery polymer (b-1), and a carboxylic acid group-containing copolymer (C) prepared by copolymerizing a specific amount of an unsaturated carboxylic acid monomer and having a number average molecular weight of 20,000-70,000, wherein the rubbery polymer (b-1) is prepared by polymerizing 25-100 mass% 1,3-butadiene and has a mass average particle diameter of 0.1-0.4μm, and the monomer component (b-2) contains 50-100 mass% methyl methacrylate and/or styrene.
