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.

Abstract: A transparent conducting film including a first and second transparent conducting layers each containing a binder resin and a nano-structured network having metal nanowire intersections, and first and second protection layers, which are sequentially formed on the first and second main faces, respectively, of a resin film containing a base resin and an ultraviolet absorbent. The resin film has a light transmittance of 10% or less in a region of wavelength 350 to 370 nm in an optical transmission spectrum, and a film of the base resin having a thickness same as the thickness of the resin film has a light transmittance of 80% or more in a region of wavelength 350 to 700 nm.
