<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a touch input sheet with a narrow frame, which is suitable for a capacitive touch sensor having a narrow frame and a two-layered transparent conductive film pattern and is superior in an anti-rust property. <P>SOLUTION: A conductive sheet formed by laminating a transparent conductive film 3, a light shielding conductive film 1, and a first resist layer in order on each of both surfaces of a transparent base sheet is used, and the first resist layers on both surfaces are simultaneously exposed and developed, and then, the transparent conductive films and the light-shielding conductive films are etched simultaneously. After the first resist layers are peeled, second resist layers which have a rust inhibitor added thereto and are patterned are laminated on the exposed light shielding conductive films, and the light shielding conductive films in only a center window portion and a terminal portion are etched to expose the transparent conductive films, and the second resist layers are left as anti-rust layers without being peeled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
