| 摘要 | PURPOSE: To raise the mounting density, suppress the cost, and enhance the reliability by covering one of the electrodes with a transparent electroconductive film formed by application of transparent electroconductive coating, and by covering the other electrode with a transparent electroconductive film prepared by physical filming method, whereover another transparent electroconductive film formed by application of transparent electroconductive coating is further laid. CONSTITUTION: One of the electrodes 26 is so formed that a transparent electroconductive film is laid on an insulation sheet 21 by vacuum evaporation, sputtering, ion plating, whereover a transparent electroconductive coating is further applied, while the other electrode 31 so formed that a transparent electroconductive coating is applied on a transparent insulation sheet 27, wherein the later one 31 has spacer function, and these two electrode sheets are laid one over the other directly. This can eliminate insensitive zones to enable to obtain of coordinates data in follow up to the handwriting without breaks even though the mounting density is raised, that is further associated with low cost.
