Abstract

An object of the present invention is to provide a method for manufacturing a touch panel. A laminated film is used. The laminated film comprises a resin layer, a protection film-constituent material layer provided on a surface of the resin layer, and a releasing layer provided on a surface of the protection film-constituent material layer. The protection film-constituent material layer is a layer containing fluorine-based substances. The releasing layer is a layer made by using a fluorine-based resin. The method comprises a molding process, a hardening treatment process for providing hardening treatment to the protection film-constituent material layer after the molding process, and a removal process for removing the releasing layer after the molding process. The protection film-constituent material layer is an uncured layer in the course of a molding process.
