    Abstract: Disclosed is a method for producing a conductive substrate wherein a metal fine particle layer is arranged on at least one side of a base in a network form. This method comprises a step for processing the metal fine particle layer with an organic solvent, and a following step for processing the metal fine particle layer with an acid. Also disclosed is a conductive substrate produced by such a method. This method enables to produce a conductive substrate, which has transparency and high conductivity and is thus suitable for electromagnetic shielding films and the like, with high yield.
