PROBLEM TO BE SOLVED: To provide a polyamide resin composition that has excellent tensile strength and tensile elasticity not only at ordinary temperature but also at high temperature, in the polyamide resin composition comprising polyamide fibers and carbon nanofibers.SOLUTION: A polyamide resin composition comprises a polyamide resin and carbon nanofibers. In the polyamide resin composition, the carbon nanofibers comprise: carbon nanofiber A whose curvature is 1.2 or more and 3.3 or less; and carbon nanofiber B whose curvature is 1.0 or more and less than 1.2. 【課題】ポリアミド繊維とカーボンナノ繊維とを含むポリアミド樹脂組成物において、常温だけでなく高温においても、引張強度、及び引張弾性率に優れるポリアミド樹脂組成物を提供すること。【解決手段】ポリアミド樹脂とカーボンナノ繊維とを含むポリアミド樹脂組成物であって、カーボンナノ繊維は、曲率が１．２以上３．３以下であるカーボンナノ繊維Ａと、曲率が１．０以上１．２未満であるカーボンナノ繊維Ｂとを含む、ポリアミド樹脂組成物。【選択図】図１
