  As one sensor layer structure for a capacitive touch panel, a layer structure in which a transparent electroconductive layer is formed on each of opposite surfaces of a single film substrate, so-called GFD structure, is used. In the structure, for sufficiently suppressing internal reflection from the transparent electroconductive layer, it is necessary to employ a technique of forming one or more refractive index adjustment (IM) layers on each of the opposite surfaces of the single film substrate. This causes a problem that production yield is likely to deteriorate, and a production cost is increased. The present invention is directed to solving such a problem and, specifically, to laminating a refractive index adjustment zone-formed pressure-sensitive adhesive layer capable of being produced easily and at low cost, to each transparent electroconductive layer of a double-sided transparent electroconductive film, so as to effectively suppress internal reflection in the resulting laminate.

  作为电容式触摸屏的一种传感器层结构，使用了一种在单膜基板的每个相对表面上形成透明导电层的层结构，即所谓的 GFD 结构。在该结构中，为了充分抑制透明导电层的内部反射，有必要采用在单膜基板的每个相对表面上形成一个或多个折射率调整（IM）层的技术。这就造成了一个问题，即生产成品率可能会降低，生产成本也会增加。本发明旨在解决这一问题，具体而言，就是在双面透明导电薄膜的每个透明导电层上层压一个折射率调整区形成的压敏胶层，该层能够以低成本轻松生产，从而有效地抑制由此产生的层压板的内部反射。
