A transparent conductive film has a polymer film 4 and a transparent conductive layer 5 formed on the polymer film 4. The transparent conductive layer includes indium oxide, a zinc oxide system and a tin oxide system. A covering layer 9, made of material different from that of the transparent conductive layer 5, is formed on the transparent conductive layer 5.
