Abstract
The present invention provides a transparent conductive film in which occurrence of scratches during sliding is suppressed even when transparent conductive layer forming surfaces are so arranged as to face each other. Provided is a transparent conductive film comprising a transparent film base; at least one dielectric layer formed on a first main surface of the transparent film base; and a transparent conductive layer formed on the dielectric layer, wherein the transparent conductive layer is patterned; and the surface on the first main surface of the transparent conductive film has an arithmetical mean roughness Ra of 22 nm or more, and has 140/mm2 or more of protrusions having heights of 250 nm or higher at a pattern-opening part in which the transparent conductive layer is not formed.
