1. A touch panel, comprising:

  • a first insulation substrate;

    a first conductive film, covering said first insulation substrate, wherein said first conductive film comprises a first side, a second side, a third side, and a fourth side;

    a first insulation layer, covering a continuous margin area along said first side, second side, and third side of said first conductive so that the first conductive film has a first exposed region uncovered by said first insulation layer;

    a first conductive wire, disposed at a first portion of the first conductive film closest to the first side, comprising;

    a first electrode segment, contacting with the first exposed region to be electrically connected to the first conductive film; and

    a first extending segment, contacting with the first insulation layer to be isolated from the first conductive film;

    a second conductive wire, disposed at a second portion of the first conductive film, comprising;

    a second electrode segment, contacting with the first exposed region to be electrically connected to the first conductive film; and

    a second extending segment, contacting with the first insulation layer along with said second side and isolated from the first conductive film;

    a dummy wire, deposited on said first insulation layer along said third side and isolated from the first conductive film;

    a second insulation substrate, wherein the second insulation substrate is for connecting with an external circuit;

    a second conductive film, covering a second surface of the second insulation substrate, wherein the second conductive film has a first region and a plurality of second regions, the first region and the second regions are separated from one another;

    a third conductive wire, disposed on the second conductive film;

    a fourth conductive wire, disposed on the second conductive film; and

    a plurality of connecting wires disposed on two or more of the second regions, wherein one of the connecting wires is extended from a corner of the first conductive film to an adjacent corner thereof, the connecting wires and one of the first conductive wires are disposed at a same side of the first insulation substrate, each of the connecting wires has an external connecting terminal and an inner connecting terminal, and the inner connecting terminals are respectively electrically connected to the second conductive wires;

    wherein the second electrode segment contacts with the first region, and the second extending segment contacts with one of the second regions.
