Abstract:
A double-sided transparent conductive film including a base material film, having an anti-blocking layer, an optical adjusting layer and a transparent conductive layer formed in this order on each of both sides of the base material film, wherein an anti-blocking layer containing particles is formed at least one of: a location between the base material film and one optical adjusting layer; and a location between the base material film and the other optical adjusting layer, the anti-blocking layer has a flat portion and protrusion portions caused by the particles, and a value obtained by subtracting a thickness of the flat portion of the anti-blocking layer from a mode diameter of the particles is larger than a thickness of the optical adjusting layer.
