決まるが、これらの構成部材の境界に空気層が存在する
ので、各部材と空気層との屈折率の違いにより、透明タ
ッチパネル全体の光透過率はきわめて小さくなる。In the transparent touch panel having such a structure, the light transmittance of the entire transparent touch panel is determined by the light transmittance of both electrode films and the supporting substrate. Since there are layers, the light transmittance of the entire transparent touch panel becomes extremely small due to the difference in refractive index between each member and the air layer.

The polyethylene terephthalate film having the hard coat layer 1 formed on the upper surface and the ITO layer serving as the movable electrode 3 formed on the lower surface was used. Further, as the fixed electrode side film 7, an ITO layer which becomes the fixed electrode 6 is formed on the upper surface of a polyethylene terephthalate film having a thickness of 100 μm, and an acrylic transparent adhesive is applied on the lower surface by a roll coater to form an adhesive layer 8. Then, a product having a release film attached thereon was used.

A spacer 4 was formed and both electrode films 2 and 7 were bonded together with a peripheral edge adhesive layer 5 according to a usual method for manufacturing a transparent touch panel. On the other hand, a polycarbonate plate having the same size as both electrode films 2 and 7 and having a thickness of 1 mm is prepared as a supporting substrate 9, and the release film of the fixed electrode side film 7 is peeled off to align with the supporting substrate 9 and under vacuum. The transparent touch panel of FIG. 1 was obtained by sticking on the entire surface.

定電極の耐久性も向上する。Therefore, since the air layer is eliminated as much as possible in the layer structure of the transparent touch panel, the light transmittance of the touch panel is large. In addition, the transparent touch panel has a display such as an LCD or an IC with an image.
When set on a card or the like, the visibility of the lower image through the transparent touch panel is high. Further, the adhesive layer has a cushioning effect against various mechanical stimuli received by the input, and the durability of the movable electrode and the fixed electrode is also improved.
