Abstract:
A transparent electrically conductive film-attached substrate comprising a transparent substrate having formed on one of surface thereof a five-layer transparent electrically conductive film having a sheet resistance of about 2.5 .OMEGA./.quadrature. or less, wherein said transparent electrically conductive film is formed by successively laminating onto said substrate a first reflection preventing layer having a thickness of 30 to 70 nm, a first metal layer comprising silver as the main component having a thickness of 5 to 30 nm, a dividing layer having a thickness of 60 to 120 nm, a second metal layer comprising silver as the main component having a thickness of 5 to 30 nm, and a second reflection preventing layer having a thickness of 30 to 70 nm, from said transparent substrate side, and wherein each of said reflection preventing layers and said dividing layer comprises a composite oxide of indium and zinc as the main component.
