PROBLEM TO BE SOLVED: To provide a polyamide resin composition that has a small expansion coefficient at the time of water absorption and a small coefficient of thermal expansion, as well as high impact strength, rigidity, electroconductivity, adhesiveness of a coating film, and moldability, and to provide an automotive exterior part comprised of the polyamide resin composition. SOLUTION: The polyamide resin composition comprises (A) a 35-90 wt.% polyamide resin, (B) a 5-35 wt.% impact resistance improving agent, (C) a 1-30 wt.% non-fibrous filler, wherein the sum amount of (A)-(C) is 100 wt.%, and the polyamide resin (A) comprises (A1) a 20-80 wt.% hexamethylene sebacamide unit obtained from sebacic acid and hexamethylene diamine, (A2) an 80-20 wt.% hexamethylene terephthalamide unit obtained from terephthalic acid and hexamethylene diamine, and (A3) a copolyamide resin.
