Abstract
A method of manufacturing a narrow frame touch input sheet having very good anticorrosion properties and suitable for a narrow frame capacitance type touch sensor having a double-layer transparent conductive film pattern. The method uses an electrical conductivity sheet obtained by sequentially forming transparent and light blocking conductive films, and first resist layers, on both sides of a transparent base sheet, exposing and developing the resist layers on both sides simultaneously, etching the transparent and light blocking films simultaneously, removing the resist layers, laminating second resist layers with anticorrosion agent on the revealed light blocking films, etching the light blocking films in center windows and terminal portions to reveal the transparent films, and side etching revealed end faces of the light blocking films at center window and terminal portion boundaries to create visor structured second resist layers that are heat softened as an anticorrosion layer on the revealed faces.
