Abstract
Disclosed is a touch panel including an upper conductive layer; a lower conductive layer facing the upper conductive layer with an interval between the upper conductive layer; a capacitive sensing unit that detects a coordinate position by a capacitive coupling under a condition where a predetermined electric potential is applied to the upper conductive layer; and a resistive sensing unit that detects a coordinate position based on an electric potential at a position where the upper conductive layer and the lower conductive layer contact under a condition where a potential gradient is generated on either one of the upper conductive layer and the lower conductive layer.
