Abstract:
A touch panel includes an upper substrate having insulating property, an upper conductive layer on a lower surface of the upper substrate, an intermediate layer on a lower surface of the upper conductive layer, an upper electrode on a lower surface of the intermediate layer, a lower conductive layer facing the upper conductive layer with a predetermined gap interposed between the conductive layers, a lower electrode on an upper surface of the lower conductive layer, and a lower substrate on a lower surface of the lower conductive layer and having insulating property. The upper and lower electrodes contain 70 wt. % to 98 wt. % of conductive metal. The intermediate layer contains a resin and 40 wt. % to 90 wt. % of carbon and has a thickness ranging from 1 μm to 50 μm. The touch panel has resistance to environment and is applicable to a large size.
