Abstract

Provided is a transparent conductive film exhibiting high conductivity together with excellent transparency, and also exhibiting film strength tolerant to a washing treatment and a pattern forming treatment while maintaining conduction to an electronic device layer formed on an transparent conductive layer. Also disclosed is a method of manufacturing a transparent conductive film possessing a transparent substrate and provided thereon, a transparent conductive layer containing a metal nanowire, possessing the steps of forming a layer containing a crosslinking agent on the substrate, coating a coating solution containing a metal nanowire onto the layer containing the crosslinking agent, drying the coating solution, and conducting a treatment by which the crosslinking agent is reacted.
