<p>PURPOSE:To aim at the prevention of any malfunction at time of inputting highly minute characters and patterns and the protection of a transparent electrode membrane by converting a transparent conductive protecting coat, consisting of specific material, on at least either surface of transparent electrode membranous surface being opposed to each other at the specified thickness. CONSTITUTION:Transparent conductive protecting coats 3 and 4 are formed on opposed surface of two transparent electrode membranes 2 and 5 constituting a membrane type touch panel 7 and the required void is interposed between them. This transparent conductive protecting coat will do at either side of 3 or 4, and the composition is ultraviolet hardening binder resing and (or) such one dispersing conductive oxide powder of 40-95 wt.% in thermosetting resin, and the covering thickness is set a range of 1-30 mum for retention of membranous strength. With this constitution, these transparent electrode membranes 2 and 5 are protected form oxidation and corrosion and, what is more, the required electrical resistance value against pressing force is maintainable so that any malfunction is avoidable.</p> |
