PROBLEM TO BE SOLVED: To provide a molded article having excellent vibration-resistant characteristics without deteriorating the appearance of the molded article, even when a large amount of a reinforcing material such as glass fibers to improve strengths and rigidity is added to a polyamide resin to sufficiently satisfy the strengths and the rigidity. SOLUTION: This polyamide resin composition comprising (A) a crystalline polyamide resin containing a polycapramide resin as a main component and/or a crystalline polyamide resin comprising hexamethylenediamine and adipic acid as main components, (B) a polyamide resin except the component (A) as a component, (C) a block copolymer comprising the block of the polymer of a vinyl aromatic compound and the block of polyisobutylene, polyisoprene, and/or isoprene-butadiene copolymer or its hydrogenation product as a component, and (D) an inorganic reinforcing material as a component is characterized by having a flexural modulus of 13 to 25 GPa and a melt flow index of 4 to 50 g/10 min.
