1. An touch panel with an electrode bridging structure, wherein the touch panel comprises an electroconductive substrate and an electroconductive film, each of opposite surfaces of the electroconductive substrate and the electroconductive film is coated with a transparent electroconductive layer, an annular electrode loop is disposed on a circumference of the electroconductive substrate, four electroconductive wires are connected to four corners of the electrode loop, a region, which is disposed between the electroconductive substrate and electroconductive film and corresponds to the electrode loop, is printed with an insulating layer and a plurality of insulators formed in an enclosed space, the electroconductive film is adhered onto the electroconductive substrate through an adhesive layer, a connection terminal portion is disposed on the electroconductive substrate, the connection terminal portion has electroconductive connection terminals connected to the electroconductive wires, respectively, a middle of the connection terminal portion has a signal connection terminal to be connected to the electroconductive film for induction conduction, and the characteristic lies in that:

  • the signal connection terminal of the connection terminal portion is connected to first ends of at least two signal wires, and a second end of each of the signal wires is formed with at least one electroconductive bridging portion, which is longitudinal and has a long axis in parallel with an X-axis or a Y-axis corresponding to an arranged position of the electroconductive bridging portion; and

    the insulating layer and the adhesive layer are formed with longitudinal through holes corresponding to the electroconductive bridging portions, respectively, so that the electroconductive bridging portions may contact with the transparent electroconductive layer of the electroconductive film.
