PROBLEM TO BE SOLVED: To provide a polyamide resin composition excellent in mechanical characteristics, fluidity during molding, thermal stability during melt retention, and oxidation degradation resistance.SOLUTION: The polyamide resin composition contains 0.005-1 pt.mass of a metal halide (B) based on 100 pts.mass of a terminal-modified polyamide resin (A). The terminal-modified polyamide resin (A) has, at a terminal group of a polymer, a structural unit different from a repeating structural unit of the main chain of the polymer. The polyamide resin (A) has terminal structures represented by formula (I): -X-(R-O)-Rand formula (II): -Y-R(Ris a C2-10 hydrocarbon; Rand Rare each independently a C1-30 hydrocarbon; X is NH, N(CH) or C=O; Y is C=O when X is NH or N(CH), and Y is NH or N(CH) when X is C=O; and m is an integer of 2-100).SELECTED DRAWING: None 【課題】機械的特性、成形加工時の流動性、溶融滞留時の熱安定性並びに耐酸化劣化性に優れた、ポリアミド樹脂組成物の提供。【解決手段】末端変性ポリアミド樹脂（Ａ）１００質量部に対し、金属ハロゲン化物（Ｂ）０．００５〜１質量部を含有するポリアミド樹脂組成物で、末端変性ポリアミド樹脂（Ａ）が、ポリマーの主鎖の繰り返し構造単位とは異なる構造単位をポリマーの末端基に有する末端変性ポリアミド樹脂であるポリアミド樹脂組成物。ポリアミド樹脂（Ａ）が式（Ｉ）及び式（ＩＩ）で表される末端構造を有する、ポリアミド樹脂組成物。−Ｘ−（Ｒ１−Ｏ）ｍ−Ｒ２・・（１）、−Ｙ−Ｒ３・・（２）（Ｒ１はＣ２−１０炭化水素；Ｒ２及びＲ３各々独立にＲ３はＣ１〜３０炭化水素；ＸはＮＨ、Ｎ（ＣＨ３）又はＣ＝Ｏ；ＹはＸがＮＨ又はＮ（ＣＨ３）の場合、Ｃ＝Ｏ、ＸがＣ＝Ｏの場合、ＮＨ又はＮ（ＣＨ３）；ｍは２〜１００の整数）【選択図】なし
