Abstract: First and second transparent conducting layers each containing a binder resin and a nano-structured network having metal nanowire intersections, are respectively formed on first and second main faces of a transparent resin film, each of the first and second transparent conducting layers has an absorption peak based on the nano-structured network in an optical transmission spectrum, the transparent resin film has a thickness of 40 μm or more. After first and second protection layers are respectively formed on the first and second transparent conducting layer, only the first transparent conducting layer is etched from the first protection layer side so that a first transparent conducting pattern having a first conducting region and a first non-conducting region is formed by the first transparent conducting layer on the first main face.
