Sectional view. The basic structure 1 includes an upper conductive layer π, a lower conductive layer 12, and a plurality of spacers 13. In the basic structure 1, the upper conductive layer 11 is made of PET (P〇lyEthyleneTerephthalate, polyethylene terephthalate), and a layer of bismuth tin oxide (IT0) is coated on the lower surface. U1. On the other hand, the material of the lower conductive layer 12 is made of PET or glass. The upper surface thereof is also coated with a layer of indium tin oxide. The upper conductive layer 11 and the lower conductive layer 12 are separated by a spacer 13 . In order to avoid a short circuit caused by no touch, a malfunction occurs.
