1. A method for the production of a thin plate-like laminate having a film-like resin layer, wherein molds are arranged on both surface sides of a workpiece in which a film-like resin composition is laminated on at least one surface of a substrate and the molds are compressed from outer surfaces of the molds to integrally form the substrate and the film-like resin composition, the method comprising the steps of:
creating a mold retention structure in which the molds, which have been heated to a thermal deformation temperature of the film-like resin composition, are arranged on both surface sides of the workpiece, the mold retention structure being slidably arranged on a rail body, and
sliding the mold retention structure in which the heated molds are arranged between two compression rollers and compressing the outer surfaces of the molds by rotating the compression rollers to integrally thermocompression-bond the film-like resin composition and the substrate to form a thin plate-like laminate having a film-like resin layer.
