Abstract

A method of producing a laminated structure includes: a laminated structure that has high adhesion strength between resin layers and that is excellent in respect of working efficiency, the method including: a lamination step of preparing an intermediate laminate in which a first resin layer and a second resin layer are laminated with an adhesive resin layer interposed between the first resin layer and the second resin layer; a first molding step of molding the intermediate laminate; and a second molding step of forming a resin member on a surface of the molded intermediate laminate by injection molding using a raw material resin to obtain a laminated structure in which at least a part of the adhesive resin layer is thermally cured to be an adhesion layer. An adhesive resin composition constituting the adhesive resin layer contains at least an acrylic-based polymer, a crosslinking agent, and a thermal polymerization initiator.
