Patent ID: 7060320

Claim:
A method for fabricating a transparent conductive film for use in a transparent touch panel in which a lower electrode and an upper electrode are stacked so as to be spaced from each other by spacers, the transparent conductive film being provided on an electrode substrate of at least one of the electrodes and thereby forming the electrode, the method comprising: forming an indium oxide-tin oxide film so that the film has, in its surface shape, an arithmetic mean roughness (Ra) within a range of 0.4 nm≦Ra≦3.0 nm and a root-mean-square roughness (Rms) within a range of 0.6 nm≦Rms≦2.0 nm, by a coating or printing process using a sol-gel material, where at least an organometallic compound constituting the sol-gel material is composed of indium and tin and has a constituent weight ratio of indium to tin that 5 wt %≦{Sn/(In +Sn)}×100≦15 wt %.
