A method of producing an extrusion-laminated member comprises extruding a thermoplastic resin from a T-die into the form of a film and laminating the film on a heated metallic base member using a pair of laminating rolls, wherein a pre-roll is disposed between the T-die and one of the laminating rolls to receive the film on the side opposite to the side that adheres onto the base member over the whole width of the film. The film is wound on the pre-roll at an angle (α) of from 10 to 90 degrees. The film received by the pre-roll is fed to the laminating rolls, conveyed by being supported by the laminating rolls on the side opposite to the side that adheres onto the base member, and is fed to a nipping position so as to be melt-adhered onto the heated metallic base member.
