Abstract
A method for producing a laminate, the method comprising at least a pretreatment step of pretreating a surface of a substrate made of a plastic film by reactive ion etching so that the maximum displacement of the substrate surface measured by local thermal analysis is 300 nm or more, and a lamination step of laminating a thermoplastic resin layer made of a material different from that of the substrate on the pretreated surface of the substrate; wherein the plastic film is a polyethylene terephthalate film.
