Abstract:
A panel-type input device including a pair of electrode plates, each electrode plate having a substrate and a conductive coat provided on a surface of the substrate, the conductive coat of each electrode plate being formed from a conducting polymer. The conductive coat of each electrode plate includes a detecting area adapted to detect a touch input and an inoperative area disposed adjacent to the detecting area, the inoperative area having a surface resistivity higher than a surface resistivity of the detecting area. A parallel electrode pair adapted to apply a voltage to the conductive coat is formed in the detecting area, and conductors connected to the parallel electrode pair are formed in the inoperative area. The inoperative area insulates the conductors from the detecting area.
