Patent ID: 8852852

Claim:
A method for manufacturing a narrow frame touch input sheet, comprising: forming and stacking transparent conductive films, light-excluding conductive electrode films, and first resist layers sequentially on both surfaces of a transparent base sheet; exposing and developing the first resist layers simultaneously on the both surfaces; etching the transparent conductive films and the light-excluding conductive electrode films on the both surfaces; stripping the first resist layers so as to form a fine wiring circuit pattern with the stacked transparent conductive film and light-excluding conductive electrode film in an outer edge portion on each of the two surfaces of the base sheet; forming a second resist layer to cover the fine wiring circuit pattern on each surface of the base sheet; and etching only the light-excluding electrode conductive film layer on which the second resist layer is not formed, so that a circuit pattern of the transparent conductive film is exposed in a central window portion on each surface of the base sheet.
