And electrically connecting the first conductor and the second conductor through the through holes respectively. In summary, in the electronic device of the present invention and the touch panel thereof, since only a single substrate is used as the double-layer structure, the fabrication can be greatly reduced, and the weight and thickness of the touch panel can be reduced. The above and other objects, features and advantages of the present invention will become more apparent from the aspects of the appended claims. 2A is a top view of a touch panel according to an embodiment of the present invention, and FIG. 2B is a side cross-sectional view of the touch panel of FIG. 2A along AA', and FIG. 2C is a touch of FIG. 2A Side view of the control panel along the BB' line. Referring to FIG. 2A φ 〜 2C, the touch panel 200 of the present invention is a double-layer board structure, and includes a substrate 210, a plurality of first conductors 220, a plurality of second conductors 230, and a plurality of first conductive wires 240.

The first conductor 220 and the second conductor 230 are formed on the front surface of the substrate 210, wherein the first conductors 220 are formed into a plurality of first axial directions X, and the second conductors 230 are formed into a plurality of second axial directions Y. . In the present embodiment, the first axial direction X is, for example, a lateral direction, and the second axial direction Y is, for example, a longitudinal direction, and the first axial directions X and the second axial directions Y are vertically interlaced with each other. Receiving the above-mentioned first conductor 220 M366120 located in the same first axial direction X, 'φ- is electrically connected through the corresponding first wire 240 in series, that is, in the same first axial direction X A conductor 220 and a first conductor 24 can form a similar, conventionally shaped lateral electrode. The insulating layer 250 covers the first conductor 22 and the first conductor 240, and partially exposes the second conductor 230 to electrically insulate the first conductor 220 from the second conductor 230. In addition, the second wire 260 is formed on the insulating layer 25 〇 and the second conductor 230 such that the second conductor 23 位于 located in the same second axial direction γ is connected in series through the corresponding first wire 260 and is electrically connected.
