GFD-type layer structures having transparent conductive layers formed on both surfaces of one substrate are used as one type of sensor layer structure for a capacitance-type touch panel. In order to sufficiently suppress internal reflection in the transparent conductive layers of such configurations, it is necessary to use a method for forming a plurality of refractive index-adjusting (IM) layers on both surfaces of the one substrate, or to form a refractive index-adjusting layer as an overcoat layer on the conductive layers having patterns formed therein, resulting in an increase in cost and a decrease in yield. In order to address such problems, the present invention layers an easily and inexpensively producible adhesive layer having a refractive index-adjusting section onto each transparent conductive layer of a double-sided transparent conductive film, and as a result, makes it possible to effectively suppress the internal reflection in a laminate. |
