Zusammenfassung:	To provide a polyamide film that significantly suppresses the warping to occur during the fabrication of a laminate, and also significantly prevents warpage or deformation even after heat treatment (e.g., reflow treatment).SOLUTION: A stretched polyamide film includes a resin composition including: a semi-aromatic polyamide (A) composed of a dicarboxylic acid component primarily comprising terephthalic acid and a diamine component primarily comprising a C9 aliphatic diamine; and crystalline polyamide (B) other than (A), where the mass ratio of (A)/(B) is 99/1-50/50.SELECTED DRAWING: None 【課題】積層体を作製した際に発生する反りがより十分に低減され、熱処理（例えばリフロー処理）後においても、反りや変形がより十分に低減されたポリアミドフィルムを提供する。【解決手段】テレフタル酸を主成分とするジカルボン酸成分と、炭素数が９である脂肪族ジアミンを主成分とするジアミン成分とからなる半芳香族ポリアミド（Ａ）と、（Ａ）以外の結晶性ポリアミド（Ｂ）を含み、（Ａ）／（Ｂ）の質量比率が９９／１～５０／５０である樹脂組成物からなる延伸ポリアミドフィルム。【選択図】なし
