Zusammenfassung:	To provide a metal foil-polyimide laminate which is preferably usable for a planar heating element and has large adhesion force and reduced variation of adhesion force without causing complication of a production process.SOLUTION: In a metal foil-polyimide laminate, a polyimide-based resin layer having the thickness of 1 to 50 μm is formed on a metal foil having the thickness of 10 to 100 μm by a casting method. The polyimide-based resin layer is polyimide-based resin synthesized by diamine compound and tetracarboxylic acid dianhydride. The diamine compound is at least paraphenylene diamine and 2,2'-dimethyl-4,4'-diaminobiphenyl. The tetracarboxylic acid dianhydride is at least pyromellitic acid dianhydride and 3,4,3',4'-biphenyl tetracarboxylic acid dianhydride. The peel strength of the metal foil is 1kN/m or more.SELECTED DRAWING: None 【課題】面状発熱体に好適に使用可能な生産プロセスの複雑化を招くことなく、密着力が大きく、かつ密着力のばらつきが低減される金属箔−ポリイミド積層体の提供。【解決手段】金属箔−ポリイミド積層体は、厚さ１０〜１００μｍの金属箔上に、キャスティング法で厚さ１〜５０μｍのポリイミド系樹脂層が形成されている。前記ポリイミド系樹脂層は、ジアミン化合物及びテトラカルボン酸二無水物から合成されるポリイミド系樹脂である。前記ジアミン化合物は、少なくともパラフェニレンジアミン及び２，２'−ジメチル−４，４'−ジアミノビフェニルである。前記テトラカルボン酸二無水物は、少なくともピロメリット酸二無水物及び３，４，３'，４'−ビフェニルテトラカルボン酸二無水物である。前記金属箔の剥離強度は、１ｋＮ／ｍ以上である。【選択図】なし
