摘要:
A touch panel to detect a coordinate of an arbitrary position where pressure is applied. The touch panel includes a substrate, a resistor layer provided on the substrate, a spacer layer made of an insulator material, a conductor layer confronting the resistor layer via the spacer layer, a plurality of point electrodes provided on the resistor layer at a peripheral part of the resistor layer along each side of the resistor layer, and a plurality of switching elements provided above the substrate and electrically coupled to the point electrodes for supplying a voltage to the point electrodes. The spacer layer is made up of a plurality of spacer pieces which are arranged so that an electrical contact is made between the conductor layer and the resistor layer when a pressure is applied at an arbitrary position on the conductor layer.
