Abstract:

An electronic device display window touch input function-equipped protection panel can suppress lowering of electric characteristic or external view quality in a lead connection portion. The electronic device display window touch input function-equipped protection panel includes: a touch panel having a flexible upper electrode and inflexible lower electrode plate which are arranged at a predetermined gap in such a manner that their electrode surfaces faces to each other and the external circumferential portions of the respective electrode plates are bonded via an insulating adhesive layer; a decoration film having a transparent window portion and bonded on the surface of the upper electrode plate; and a pin-equipped lead for extracting an electric signal from the electrode terminal of the electrode plate via respective metal pins inserted into a plurality of through holes arranged on the lower electrode plate. A rubber-based conductive adhesive agent layer is formed on the electrode terminal of one of the upper electrode plate or the lower electrode plate as a primary coating of the conductive adhesive agent introduced into the respective through holes.
