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.
