ものである。Detailed Description of the Invention Technical Field The present invention relates to a transparent membrane touch panel in which a flexible upper transparent substrate provided with a transparent electrode and a lower transparent substrate provided with a transparent electrode are opposed to each other with a certain gap provided therebetween. It is something.

いう工程で行っている。<Prior art> Conventionally, as a method for forming transparent electrode patterns on the upper and lower substrates of a transparent membrane touch panel, first, an ITO film is formed on the entire surface of the substrate by vapor deposition or sputtering,
Thereafter, an acid-resistant resist is printed in a predetermined pattern by screen printing or the like, the exposed portion of the ITO film is etched with an acidic solution, and then the resist is peeled off.

ものとなっていた。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, and the life of the touch panel as a switch is shorter than that of other mechanical switches. It was a short one.

ある。<Object of the Invention> The present invention aims to solve the above-mentioned problems of the prior art. To provide a transparent metsuprene type touch panel in which the resist is left as it is without peeling and is used as a protective film for a transparent electrode to extend the life of a dot as a switch.

伸びた。A 100 μm thick PET film with an ITO film was used as the upper substrate, a 1 mm thick glass with an ITO film was used as the lower substrate, and a polyester resin containing ITO fine powder was used as the transparent conductive paint. When we created a touch panel, the dot life was 92 times longer than that of conventional products.
