Abstract
Disclosed is a method for producing a transparent conductive film comprising a coating step for coating a coating solution containing metal nanoparticles on a substrate to form a coated layer, a drying step for drying the coated layer and a baking step for baking the coated layer to obtain a transparent conductive film, wherein a metal in the metal nanoparticles is oxidized to a metal oxide during at least one of the coating step, the drying step and the baking step. According to this method, a transparent conductive film having a low specific resistance and a high light transmittance can be produced by coating.
