Abstract
A touch panel in which warpage due to a difference in the linear expansion coefficient between resin layers is reduced while achieving reduction in thickness and weight by using a multi-layered resin base material. A capacitive touch panel includes a transparent resin base material; a transparent resin layer formed on the front surface of the transparent resin base material; a decorative printed layer formed on an outer edge of the back surface of the transparent resin base material; and a warp prevention layer formed so as to extend and cover over the back surface of the transparent resin base material and the decorative printed layer.
