ABSTRACT:
A touch input function-equipped protection panel for an electronic device display window which can suppress deterioration of electric properties and appearance quality in a lead wire connection part, includes a touch panel having a flexible upper electrode plate and an inflexible lower electrode plate arranged face-to-face at a prescribed gap in a manner that the electrode surfaces are directed to inside and being formed by sticking the outer circumferential parts of the respective electrode plates with an insulating adhesive layer interposed therebetween; a decorative film having a transparent window part and stuck to the surface of the upper electrode plate; and a pin-equipped lead wire for extracting an electric signal from an electrode terminal of the electrode plate through respective metal pins inserted into a plurality of through holes formed on the lower electrode plate, wherein an elastomeric binder-containing conductive adhesive layer is formed on the electrode terminal of at least one of the upper electrode plate and the lower electrode plate as an underlayer of a conductive adhesive to be injected into the respective through holes.
