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.

Double-sided transparent conductive film and touch panel

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.

A transparent conductive film includes a film base, a cured resin layer formed at one side of the film base, and an indium composite oxide layer laminated at a side of the cured resin layer opposite to the film base. The indium composite oxide layer has a thickness of 20 nm to 50 nm. The cured resin layer has a plurality of spherical particles and a binder resin layer which fixes the plurality of spherical particles to the film base. A difference w&#x2212;d between a mode particle size w and a thickness d of the binder resin layer is greater than zero and less than or equal to 1.2 &#x3bc;m, where w is a mode particle size of the spherical particles and d is a thickness of the binder resin layer.
