PROBLEM TO BE SOLVED: To provide a multilayer laminate comprising a fluorocarbon resin and a thermoplastic resin which is excellent in interlayer adhesion and productivity. SOLUTION: The multilayer laminate including a laminate (I)/(II) in which a layer (I) of the fluorocarbon resin (A) having polar functional groups (a) and a layer (II) of the thermoplastic resin (B) having polar functional groups (b) are laminated directly by a means such as heating lamination is used. The melting point of the fluorocarbon resin is as low as 120-230°C. In the multilayer laminate, the layer (I) of a fluorocarbon resin having acid anhydride residues (for example, a tetrafluoroethylene/ethylene/hexafluoropropylene/(perfluorobutyl) ethylene/itaconic anhydride copolymer) and the layer (II) of an ethylene-vinyl acetate copolymer having acetoxyl groups are heat-laminated directly.
