Please refer to the fourth figure. The first substrate (2〇) is made of flexible polyimide (PI) and has a first surface (22), because the first substrate I5 (20) is used as a touch panel (1〇) The bottom layer is replaced by a hard substrate, such as a glass substrate. The first wires (3 turns) are made of copper and have a long rectangular shape and are disposed in parallel with each other on the first surface of the first substrate (20). (22) The second substrate (40) is also made of flexible polyplyimide (pI) 20 having a second surface (42) opposite the first surface (22). The second wire (50) of the 5th 4 is also made of a long rectangular shape made of copper, and is disposed in parallel with each other on the second surface (42) of the second substrate (4〇), and the extension direction of the second wire (5〇) The extension direction of a wire (3 turns) is vertically staggered.
