Abstract: 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.

Abstract: Provided are a narrow frame touch input sheet, manufacturing method of same, and conductive sheet used in the narrow frame touch input sheet that are suitable for a capacitive touch sensor of a narrow frame for which a conductive transparent film pattern has two layers. A conductive sheet is used which is provided with one or a plurality of layered transparent base sheets; and a conductive transparent film, a light-excluding conductive film for electrode use, and a first resist layer which are formed to be sequentially layered on the top surface and the rearmost surface thereof. Both sides of the first resist layer are exposed simultaneously, and after development, the conductive transparent film and the light-excluding conductive film for electrode use are simultaneously etched, the first resist layer is stripped away, then a second resist layer is formed as a coating over external bounding edge portions of both sides, and only the light-excluding conductive film for electrode use of the central window portion is etched. A circuit pattern of the conductive transparent film is thereby formed by being exposed.

Abstract: PROBLEM TO BE SOLVED: To provide a narrow frame touch input sheet with a protection film and a laminate narrow frame touch input sheet with a protection film which are suitable for a capacitance type touch sensor with a narrow frame and a two-layered transparent conductive film pattern and a method for manufacturing them.
SOLUTION: A transparent conductive film, a light shielding conductive film for electrode, and a first resist layer are successively formed on the both faces of a base sheet, and the first resist layer is simultaneously exposed and developed on the both faces, and the transparent conducive film and the light shielding conductive film for an electrode are simultaneously etched, and the first resist layer is peeled, so that a thin wire leading circuit pattern in which the transparent conductive film and the light shielding conductive film for an electrode are laminated can be formed at the external frame sections of the both faces of the base sheet, and after that the both face thin wire leading circuit pattern is coated with a second resist layer, and only the light shielding conductive film for an electrode on which the second resist layer is not formed is etched so that the circuit pattern of the transparent conductive film can be formed, so as to be exposed at each of the both face central window portions, and the light transmitting protection film is laminated.
