Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition for producing automotive exterior parts, having excellent fluidity, impact resistance, dimensional stability, rigidity, heat-resistant rigidity, conductivity, coating adhesivity, appearance and retention stability. SOLUTION: The thermoplastic resin composition for automotive exterior parts comprises (A) a polyamide 6 resin having a specific viscosity number and the ratio of a terminal carboxy group concentration to terminal amino group concentration of 2-6, (B) a hydrogenation product of a block copolymer of a vinyl aromatic compound and a conjugated diene-based compound, (C) 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) conductive carbon black having specific physical properties, (E) talc having an average particle diameter of 0.5-10μm, (F) a phosphonite compound, (G) an ethylene-vinyl alcohol resin and (H) a pentaerythritol type phosphite.
