(57) [Abstract] [Problem] Excellent in durability, chemical resistance, gas barrier property, Provided is a transparent conductive substrate having good transparency, optical isotropy, and adhesion between layers, and having high insulating surface resistance after etching a transparent conductive layer. The laminated film includes a transparent polymer substrate (S) and a cured resin layer (U), and a transparent conductive layer (E) disposed in contact with the cured resin layer (U) of the laminated film. And a transparent conductive substrate satisfying the following (a) to (e). (A) The total light transmittance is 80% or more. (B) The thickness of the transparent polymer substrate (S) is 0.01 to 1.0. mm (c) The retardation of the transparent polymer substrate (S) is 20 (d) The thickness of the transparent conductive layer (E) is 1 nm to 1 μm. (e) The surface of the cured resin layer (U) in contact with the transparent conductive layer (E) has a surface resistance value of 50 ° C. and 30% RH. Is 1.0 × 10 13 Ω / □ or more, and the surface resistance under a 50 ° C. 90% RH environment is 1.0 × 10 12 Ω / □ or more. |
