PROBLEM TO BE SOLVED: To provide a polyamide resin composition which has high vibration resistance characteristics, that is, very high resonance frequency, and which can provide a molded article that can keep high resonance frequency particularly even when absorbing water.SOLUTION: The polyamide resin composition is composed of a copolymerized polyamide resin (A) and a glass fiber (B) having a cross sectional area of 1.5-5.0×10cmand has a weight ratio ((A):(B)) of the copolymerized polyamide resin (A) and the glass fiber (B) of 20:80 to 35:65. The copolymerized polyamide resin (A) contains a decane terephthalamide unit (a) and an undecane amide unit and/or a dodecane amide unit (b), where the content of the decane terephthalamide unit (a) and the content of the undecane amide unit and/or the content of the dodecane amide unit (b) in the copolymerized polyamide resin (A) are 50-98 mol% and 50-2 mol% respectively relative to 100 mol% of the total content of the unit (a) and the unit (b). |
