Abstract
A touch panel-use transparent conductive laminate film little in coloring of transmitted beam and high in transmittance. The transparent conductive laminate film (100) comprises an intermediate layer (B) laminated on a transparent substrate(A) and having an optical film thickness of 100-175 nm, and a conductive layer (C) having an optical film thickness of 10-60 nm, the refractive index of the intermediate layer being between that of the substrate and that of the conductive layer at 1.7-1.85.
