Abstract: PURPOSE:To provide a touch switch having a high visibility and a good sliding property in inputting with which a secure interval between transparent conductor film layers can be obtained at other times than in inputting. CONSTITUTION:An ITO film is formed by sputtering on a polyethylene terepthalate film of 125mum to obtain a movable side contact plate. Next, a layer of ink is formed on a soda glass plate coated with SiO2 using ITO forming liquid including polyester, isocyanate, and ITO fine powders. Bridged polystylene fine powders of a diameter of 5mum are then blown to it for high polymer fillers, and it is heated at 120 deg.C for 1 hour for an ink layer part to be a transparent conductive film layer, so a fixed side contact plate having a high polymer filler part for a spacer can be obtained. Both contact plates are disposed to face both transparent conductive film layers with each other, and have a predetermined interval between both transparent conductive film layers by a spacer, thereby a touch switch can be provided.
