    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.
