ABSTRACT:
A transparent electroconductive film of lower resistance with a smaller content of remaining organic components and less pinholes than those of the conventional transparent electroconductive film is produced by applying a coating solution selected from (a) a coating solution comprising an inorganic indium compound free from a photosensitive group in the molecule or an inorganic tin compound free from a photosensitive group in the molecule, an organic ligand, and an organic solvent, (b) a coating solution comprising an organic indium compound free from a photosensitive group in the molecule, or an organic tin compound free from a photosensitive group in the molecule, and an organic solvent, and (c) the coating solution (a) or (b) further containing a dopant to the surface of a substrate, thereby forming a film thereon, and then irradiating the substrate with radiation capable of exciting organic groups, for example, ultraviolet rays in a state where the substrate is kept at a high temperature (100.degree.-600.degree. C.), and then baking the substrate at a high temperature.
