A hard coat layer 1 was formed on the upper surface of a μm polyethylene terephthalate film, and a movable electrode 3 of ITO was formed on the lower surface. In addition, as the fixed electrode side film 9, an ITO fixed electrode 6 is formed on the upper surface of a polyethylene terephthalate film with a thickness of 100 μm, and an acrylic transparent adhesive is applied to the lower surface with a roll coater to form an adhesive layer. A mold release film was pasted on top.

明タッチパネル全体の光透過率は７１％であった。Next, the release film of the fixed electrode side film 9 is peeled off, aligned with the surface of the support substrate 11 on which the low reflection layer 8 is not formed, and adhered under vacuum to form the transparent touch panel of FIG. Obtained. The light transmittance of both electrode films 2 and 9 used in the transparent touch panel was 85% at 550 nm. Furthermore, the light transmittance of the polycarbonate plate used as the support substrate 11 and subjected to low reflection treatment on one side was 94%. The light transmittance of the entire transparent touch panel was 74%. Note that the light transmittance of the entire transparent touch panel without the conventional low reflection layer 8 having the configuration shown in FIG. 3 was 71%.

In this case, since there is no friction with the display surface located below the transparent touch panel, this is a useful configuration for improving light transmittance.
