Abstract
A narrow frame touch input sheet, and a conductive sheet used in the narrow frame touch input sheet, are suitable for a capacitive touch sensor having a narrow frame and two layers of transparent conductive film patterns. The conductive sheet includes one or more transparent base sheets stacked into a layer, transparent conductive films, light-excluding conductive electrode films, and first resist layers, which are layered sequentially on the uppermost and lowermost surfaces thereof. The first resist layers are exposed simultaneously on both surfaces, and after development, the transparent and light-excluding conductive electrode films are simultaneously etched, the first resist layers are stripped away, then second resist layers are formed as coating on the both surfaces in an outer edge portion, so that the light-excluding conductive electrode films are etched only in the central window portions. Thus, circuit patterns of the transparent conductive films are exposed.
