PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition for producing automotive exterior parts. SOLUTION: The resin composition comprises (A) 18-80 wt.% of a polyamide 6 resin having a viscosity number measured in conformity to ISO-307 of 80-120 ml/g and the ratio of a terminal carboxy group concentration to terminal amino group concentration of ≤6 and ≥2, (B) 5-25 wt.% of a hydrogenation product of a block copolymer of a vinyl aromatic compound and a conjugated diene-based compound, (C) 3-15 wt.% of a hydrogenation product of a block copolymer of a vinyl aromatic compound and a conjugated diene-based compound, graft modified with 2.6-5.0 wt.% of maleic anhydride, (D) 1-5 wt.% of conductive carbon black having a BET specific surface area of ≥600 m<SP>2</SP>/g and a DBP oil absorption of ≥300 ml/100 g, (E) 10-30 wt.% of talc having an average particle diameter of 0.5-10 μm, (F) 0.1-1 wt.% of a pentaerythritol type phosphite compound and (G) 0.5-5 wt.% of an ethylene-vinyl alcohol resin (100 wt.% of the total of all the components).
