Abstract

PURPOSE:To provide a good design spacer for electrodes at low cost by forming a retinal point spacer on the surface of a translucent electrode by means of offset or gravure printing. CONSTITUTION:A base film 2A which is transparent and electrically insulative is provided on the surface of membrane switch resin 1, and a contact 3A consisting of transparent electrode, which is transparent and electrically conductive, is provided on the rear surface of this base film 2A. On the mating surface of this contact 3A, another base film 2B is provided which is equipped on the surface with a contact 3B similar to the contact 3A. On either base film 2A, 2B, a retinal point spacer 4 as spacer for electrodes is printed on the whole surface of transparent electrode or on the contacts 3A, 3B using a clear and electrically insulative ink by means of offset or gravure printing. This accomplishes a good design spacer for electrodes at low manufacturing cost.

ある。(Effects of the Invention) According to the method for forming an electrode spacer of the present invention, when offset printing is used as the method for forming the spacer, the viscosity of the ink is high and the viscosity can be easily controlled. Furthermore, the reproducibility of halftone dot shapes is excellent, and when 15 plates are used, manufacturing costs are low. In addition, since the spacer is formed by halftone dots, it is not as noticeable in appearance as conventional dot spacers, has excellent design, and has the advantage of preventing Newton's rings from forming when used for transparent electrodes, etc. . In addition, it is possible to accurately manage the load of manual labor simply by changing the area ratio of the halftone dots, and it is possible to perform continuous manual labor using analog methods, which was not possible when using dot spacers. Furthermore, since the spacer can be manufactured very thinly, there is an advantage that the switch can be easily made thin.
