There is provided a transparent conductive film which comprises: a film substrate; a plurality of transparent conductor patterns formed on the film substrate; and a pressure-sensitive adhesive layer wherein the transparent conductor patterns are embedded. The plurality of transparent conductor patterns respectively have a two-layer structure wherein a first indium tin oxide layer and a second indium tin oxide layer are laminated on the film substrate in this order, and the first indium tin oxide layer has a greater tin oxide content than the second indium tin oxide layer does. The first indium tin oxide layer has a smaller thickness than the second indium tin oxide layer does.

Transparent conductive film

Provided is an optical unit for a display panel device with a capacitive touch input function. In the optical unit, a touch panel laminate comprises: an optically transparent first substrate layer laminated to one surface of a transparent adhesive layer; a first transparent electrically conductive layer laminated, through a first undercoat layer, to a surface of the first substrate layer on a side opposite to the adhesive layer; an optically transparent second substrate layer laminated to the other surface of the adhesive layer; and a second transparent electrically conductive layer laminated, through a second undercoat layer, to a surface of the second substrate layer on a side opposite side to the adhesive layer.
