Abstract
In a touch panel, one of conductive layers on a bottom of an upper substrate and on a top of a lower substrate is formed of belt-shaped conductive layers. The other is a single conductive layer facing the belt-shaped conductive layers. The single conductive layer is provided with a pair of electrodes in positions corresponding to both ends in a direction where the belt-shaped conductive layers extend. When the upper substrate is pressed while a voltage is applied between the pair of electrodes, the top and lower conductive layers contact with each other. Then, a voltage value corresponding to the pressed position in the direction where the belt-shaped conductive layers extend is generated from any of the belt-shaped conductive layers. From the voltage value and the position of the belt-shaped conductive layer from which the voltage value is generated, a pressed position on the upper substrate can be detected.
