Abstract
Provided are a double-sided transparent conductive film which has blocking resistance and a low reflectance, and is inhibited from scattering reflected light to exhibit good visibility; a roll thereof; and a touch panel. The double-sided transparent conductive film of the present invention includes a base material film with an optical adjusting layer laminate and a transparent conductive layer formed in this order on each of both sides, the optical adjusting layer laminate including two or more optical adjusting layers, wherein the optical adjusting layers have different refractive indexes in each of the optical adjusting layer laminates, an anti-blocking layer containing particles is formed between the base material film and at least one of the optical adjusting layer laminates, the anti-blocking layer includes a flat portion, and a protrusion portion resulting from the particles, a value obtained by subtracting a value of a thickness of the flat portion of the anti-blocking layer from a value of a mode diameter of the particles is larger than a value of a thickness of the optical adjusting layer laminate, and the optical adjusting layer laminates each have a thickness of not less than 60 nm and not more than 250 nm.
