1. A touch panel comprising:

  • 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 come into contact under a condition where a potential gradient is generated on either one of the upper conductive layer or the lower conductive layer.
