摘要： Provided are a narrow frame touch input sheet, manufacturing method of the same, and conductive sheet used in the narrow frame touch input sheet, which are suitable for a capacitive touch sensor having a narrow frame and two layers of transparent conductive film patterns. The method uses the conductive sheet including 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 the both surfaces, and after development, the transparent conductive films and the 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.

摘要： Provided is a method of manufacturing a narrow frame touch input sheet that is suitable for a capacitance type touch sensor having a narrow frame and a double-layer transparent conductive film pattern, and has a very good anticorrosion property. The method includes using an electrical conductivity sheet obtained by sequentially forming transparent conductive films, light blocking conductive films, and first resist layers on both sides of a transparent base sheet, exposing and developing the first resist layers on both sides simultaneously, etching the transparent conductive films and the light blocking conductive films simultaneously, removing the first resist layers, laminating second resist layers with anticorrosion agent added and patterned on the revealed light blocking conductive films, etching only the light blocking conductive films in center windows and terminal portions so that the transparent conductive films are revealed, and further performing side etching of revealed end faces of the light blocking conductive films at boundaries with the center windows and with the terminal portions so that the second resist layers have a visor structure. Finally, the second resist layers of the visor structure are softened by heat treatment so as to cover the revealed end faces of the remaining light blocking conductive films, and in the same state, the second resist layers are not removed but are left as an anticorrosion layer.
