<p>PROBLEM TO BE SOLVED: To provide an input device capable of freely setting the size of a key, capable of increasing yield, which can be easily manufactured. SOLUTION: An upper electrode 2 is formed by means of thin film of metal oxide, metal thin film such as gold, silver, copper, Al, etc., or metal wire, etc. on the opposite face side of a board 1. For a seal 3, adhesives or adhesive compounds such as silicone, polyester, or urethane are used. For a lower board 4, ITO, SnO2 thin films, etc., formed by a sputter method, evaporation method, a CVD method, etc., are formed as a lower electrode 5 on the opposite face. On the opposite face to the lower board 4 of the upper board 1, a fine dot spacer 6 in the whole inside area of the seal 3 is formed using offset printing, screen printing, photogravure printing, etc.</p> |
