Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyamide resin composition excellent in adhesion with semi-aromatic polyamide and durability.SOLUTION: The polyamide resin composition is provided that contains aliphatic polyamide and an impact-resistant material, and no plasticizer. A melt viscosity of the polyamide resin composition when measured at 310°C and shear rate of 243.2 s(243.2 1/s) using a capillary flow tester is 400-700 Pa s. The aliphatic polyamide contains at least one polyamide having a terminal amino group concentration larger than a terminal carboxyl group concentration.SELECTED DRAWING: None 【課題】半芳香族ポリアミドとの接着性及びその耐久性に優れるポリアミド樹脂組成物を提供することにある。【解決手段】脂肪族ポリアミドと耐衝撃材を含み、かつ、可塑剤を含まないポリアミド樹脂組成物であり、キャピラリーフローテスターを用いて、３１０℃、２４３．２ｓ−１（２４３．２１／ｓ）の剪断速度で測定したときの溶融粘度が４００〜７００Ｐａ・ｓであるポリアミド樹脂組成物である。前記脂肪族ポリアミドは、末端アミノ基濃度が末端カルボキシル基濃度より大きいポリアミドを少なくとも１種含むポリアミド樹脂組成物。【選択図】なし
