PURPOSE: A piezoresistive touch panel and a manufacturing method are provided to change a resistance value in proportion to the pressure which is applied to a piezoresistive film, thereby utilizing the piezoresistive touch panel as a multifunctional touch sensor. CONSTITUTION: A graphene flake solution, which disperses a graphene flake, is manufactured. A graphene layer is manufactured by filtering the graphene flake solution. An intermediate layer is formed on a substrate. The graphene layer is formed on the intermediate layer. A graphene pattern layer (25) is formed on the intermediate layer by patterning the graphene layer. A polymer film (26) including the graphene pattern layer is formed by curing a polymer solution after spreading the polymer solution to the intermediate layer. The polymer film having the graphene pattern layer is separated from the intermediate layer. |
