1. A touch panel comprising:

  • a top substrate;

    a top conductive layer provided on the top substrate;

    a pair of top electrodes provided on the top substrate and extending from both ends of the top conductive layer;

    a bottom substrate;

    a bottom conductive layer provided on the bottom substrate so as to face the top conductive layer with a prescribed clearance;

    a pair of bottom electrodes provided on the bottom substrate and extending from both ends of the bottom conductive layer in a direction perpendicular to an extending direction of the top electrodes;

    a frame-like spacer formed on peripheries of the top substrate and the bottom substrate therebetween; and

    at least one ofa first separate area insulated from the top conductive layer, the first separate area being provided near an inner periphery of the spacer on a surface of the top substrate, the surface being provided with the top conductive layer, and the first separate area extending to a direction perpendicular to the extending direction of the top electrodes anda second separate area insulated from the bottom conductive layer, the second separate area being provided near an inner periphery of the spacer on a surface of the bottom substrate, the surface being provided with the bottom conductive layer, and the second separate area extending to a direction perpendicular to an extending direction of the bottom electrodes.
