で行つている。<Prior art> Conventionally, the method for forming transparent electrode patterns on the upper and lower substrates of a transparent membrane touch panel is to first form an ITO film on the entire surface of the substrate by vapor deposition or sputtering, and then to form a predetermined pattern by screen printing or the like. The process involves printing an acid-resistant resist, etching the exposed portion of the ITO film with an acidic solution, and then peeling off the resist.

式スイツチに比べて短いものとなつていた。 However, in the touch panel manufactured by this process, switching is performed by contact between the ITO films of the upper and lower substrates, so cracks in the ITO film occur, resulting in a short life span as a switch compared to other mechanical switches. It had become a thing.
