Zusammenfassung:PROBLEM TO BE SOLVED: To provide a heat-fusible polyimide film excellent in heat resistance and adhesiveness to metal, a production method of the heat-fusible polyimide film, and a polyimide metal laminate using the heat-fusible polyimide film.SOLUTION: A heat-fusible polyimide film is a multilayer film including a heat-fusible polyimide layer and a heat-resistant polyimide layer laminated in contact with the heat-fusible polyimide layer. The heat-fusible polyimide layer contains 50 mol% or more of 3,3',4,4'-biphenyl tetracarboxylic dianhydride in the entire tetracarboxylic acid dianhydride component, and contains over 50 mol% of 2,2-bis[4-(4-aminophenoxy)phenyl]propane in the entire diamine; and the heat-resistant polyimide layer contains 50 mol% or more of 3,3',4,4'-biphenyl tetracarboxylic dianhydride in the entire tetracarboxylic acid dianhydride component. The film shows a peel strength of 0.5 N/mm or more measured by the method of JIS C6471. 【課題】 耐熱性に優れ、かつ金属との接着性に優れた熱融着性ポリイミドフィルム、熱融着性ポリイミドフィルムの製造方法及び熱融着性ポリイミドフィルムを用いたポリイミド金属積層体を提供する。【解決手段】 熱融着性ポリイミド層と、前記熱融着性ポリイミド層に接して積層された耐熱性ポリイミド層とを含む多層の熱融着性ポリイミドフィルムであって、熱融着性ポリイミド層は、全テトラカルボン酸二無水物成分中、3,3',4,4'−ビフェニルテトラカルボン酸二無水物を50モル%以上含み、全ジアミン中、2,2−ビス[4−(4−アミノフェノキシ)フェニル]プロパンを50モル%超含み、耐熱性ポリイミド層は、全テトラカルボン酸二無水物成分中、3,3',4,4'−ビフェニルテトラカルボン酸二無水物を50モル%以上含み、JIS C6471の方法で測定した剥離強度が0.5N/mm以上であることを特徴とする熱融着性ポリイミドフィルム。【選択図】 なし
