A transparent substrate 1 made of a PET film (a polyester film may also be used), a transparent electrode 5 such as IT("), etc.
．． 1 is formed into a thin film by sputtering, and first, IT is applied to the transparent electrode 5 in a transparent silicone resin (manufactured by Toshi Silicone Co., Ltd., trade name: SE 700).
30 [%1
The transparent pressure-sensitive conductive elastomer layer 2 obtained by mixing is uniformly scattered (it may be formed by a screen printing method).
A pressure-sensitive touch panel is constructed by attaching the transparent substrate 1 on the elastomer layer 2 with the electrode surface of the transparent substrate 1 facing the mating electrode surface.

為に、表示装置の表示面」二に添着して使用することが
できる。<Effects of the Invention> The pressure-sensitive touch panel of the present invention can be used by being attached to the display surface of a display device because the side substrates, electrodes, and the elastomer layer interposed therebetween are all transparent. I can do it.

ことかでき、動作か頗る確実であるなど優れた効果を有
する。Since the elastomer layer interposed between the electrodes has elasticity, it becomes energized when pushed, but when the external pressure is released, its restoring force allows it to immediately return to the non-energized state, which makes it difficult to operate. It has excellent effects such as being reliable.
