ABSTRACT:
A transparent conductive film has a polymer film4and a transparent conductive layer5formed on the polymer film4. The transparent conductive layer includes indium oxide, a zinc oxide system and a tin oxide system. A covering layer9, made of material different from that of the transparent conductive layer5, is formed on the transparent conductive layer5. A touch panel is provided with the transparent conductive film as its upper electrode6A or lower electrode. The surface of the transparent conductive layer is covered with the covering layer, so that physical or chemical stresses generated during the input to the touch panel do not affect transparent conductive layer directly, thus preventing damages and delamination of the transparent conductive layer. Furthermore, the covering layer formed on the transparent conductive layer improves the strength of the transparent conductive film, thereby enhancing a resistance to wear.
