PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition which exhibits good chemical and heat resistance, particularly an improved dimensional stability by lowering the linear expansion coefficient to avoid problems liable to occur, when it is used in combination with metallic parts and is excellent in impact resistance, rigidity and appearance. SOLUTION: The thermoplastic resin composition is obtained by blending, in a specific ratio, component (A): a polyamide resin, component (B): a hydrogenated product of the block copolymer of a vinyl aromatic compound polymer block (a) and a conjugated diene-based compound polymer block (b) and/or an ethylene-α-olefin-based copolymer, component (C): a modified hydrogenated block copolymer in which 0.3-2.5 pts.wt. of an unsaturated acid and/or its derivative is added to 100 pts.wt. of the hydrogenated product of the block copolymer of the vinyl aromatic compound polymer block (a) and the conjugated diene-based compound polymer block (b), and component (D): a tabular and/or needle-shaped inorganic filler with an average particle diameter of≤8μm.
