Abstract

PURPOSE:To raise durability without causing defects due to static electricity, by providing a protective layer between a conductive layer and a mask. CONSTITUTION:A transparent conductive thin film layer 2 made of a material selected from Mo, Ta, Nb, Ti, Cr, V, W, Zr, Au, In2O3, and SnO2; a transparent protective layer 3, resistant to chemicals, made of a material selected from Al2O3, CaO, MgO, SiO2, CeO2, and TiO2; and a mask 4 formed into a pattern made of a material selected from Cr, Cr2O3, Si, Ta2O3, Ta, and Fe2O3 are successively formed on a transparent substrate 1, thus permitting the conductive film layer 2 to be made hardly destructible, the maks 4 to be made easily washable, and durable without causing defects due to conductivity change and static electricity.
