Abstract:
Provided is a metal nanowire-containing transparent conductive film that can efficiently inhibit scattering of external light at a display screen such as a touch panel, and improve black floating prevention (photopic contrast) and electrode pattern non-visibility. Also provided are a method for producing the transparent conductive film, an information input device including the transparent conductive film, and an electronic device including the transparent conductive film. The transparent conductive film includes one or more metal nanowires and the number of metal nanowire bundle structures present in the transparent conductive film is 3 or fewer per each rectangular area region of 30 μm in height and 40 μm in width of the transparent conductive film.
