Title: Process for production of laminated member

Abstract: A laminated member comprising a metal foil or sheet (1) and a thermoplastic resin film (4) bonded together with an adhesive selected from a carboxyl group-containing polyolefin and a polyolefin based resin prepared by heat-compounding a carboxyl group-containing polyolefin and a metal compound is heated at a higher temperature than the melting temperature of the adhesive and pressed using a heating roll (3) and a nip roll (6). The laminated member is then cooled at the heat distortion temperature of the adhesive or at a temperature higher than the heat distortion temperature while applying a pressure of at least 0.2 kg/cm² with a cooling roll (10) and a nip roll (11).
