1. A capacitive touch panel comprising:

  • a transparent substrate;

    a plurality of first transparent electrodes extending in a first direction on one side of the substrate; and

    a plurality of second transparent electrodes extending in a second direction crossing the first direction on the one side of the substrate with the first electrodes disposed thereon;

    wherein at each of crossing portions between the first electrodes and the second electrodes, adjacent electrodes of the second electrodes have no interruption, adjacent electrodes of the first electrodes are interrupted, and the adjacent electrodes of the first electrodes are connected by a bridge electrode;

    wherein at each of the crossing portions, an interlayer insulting film is disposed between the bridge electrode and the second electrodes;

    wherein the bridge electrode is constituted by a material containing an element, which is more susceptible to oxidation than the elements contained in a material constituting the second electrodes;

    wherein a constant voltage is applied to the first electrodes; and

    wherein a pulse voltage is applied to the second electrodes, the pulse voltage having a low potential equal to or higher than the potential of the first electrodes.
