Therefore, air is supplied from the air reservoir to the gap between the conductive films as needed. Therefore, even when the film is suddenly pushed or the external pressure changes, the pressure in the gap between the conductive films is maintained at the same level as the external pressure, and the change in the pressure prevents the film from sticking. Further, since the air reservoir is not in communication with the outside, moisture and moisture do not enter between the conductive films from the outside.

First, the configuration will be described. 1A and 1B, the transparent touch panel has a substantially rectangular parallelepiped shape, and a plurality of spacers 3 are provided at regular intervals between transparent films 1 and 2 provided above and below.
Is provided. Between these spacers 3, transparent conductive films 4, 4 are provided facing each other at a distance of 20 to 40 μm. Further, a reinforcing plate (substrate) 6 for reinforcement made of transparent acrylic is provided below the transparent film 2, and the transparent film 2 and the reinforcing plate 6 are adhered to each other by an adhesive 8 at a peripheral portion. The upper and lower transparent films 1 and 2 are filled with a sealing material 7 at their peripheral portions and adhered to each other to form a sealed structure. Further, terminals 10 for applying a voltage to the transparent conductive films 4 and 4 and outputting a signal to the outside,
11 is provided, and is configured to operate as an input device by extracting a change in the distance between the transparent conductive films 4 and 4 caused when external pressure is applied to the transparent film 1 as an electric signal.

Through a U-shaped cut 7a from the transparent film 1, 2
Flows in between. Since the groove 6a has a sufficiently large volume as compared with the volume between the transparent films 1 and 2, the groove 6a
Part of the air in a flows in, and the pressure drop between the transparent films 1 and 2 is eliminated and the transparent films 1 and 2 do not stick. Thus, the transparent film 1,
2 is maintained at a predetermined pressure, and the air flow for this only moves within the space formed between the groove 6a of the reinforcing plate 6 and the transparent film 1 or 2. Is not communicated with the outside, so that moisture does not enter the inside of the transparent touch panel. In the above embodiment, the transparent touch panel has been described as an example of the touch panel. However, the present invention is not limited to the transparent touch panel.

In addition, since the air reservoir is isolated from the outside air, moisture and humidity are prevented from entering the touch panel, thereby improving reliability. Furthermore, no special parts are required,
Reliability can be improved without increasing costs.
