Abstract: Provided is a transparent conducting film having a preferable optical property, a preferable electrical property, and further, a superior durability of folding. The transparent conducting film comprises a transparent substrate and a transparent conducting layer formed on at least one of main faces of the transparent substrate, wherein the transparent conducting layer contains a binder resin and a conducting fiber, a cut portion of the transparent conducting film has a straightness of 0.050 mm or less. Preferably, the transparent substrate is a resin film having an elongated resin film or cut out from an elongated film, and can be folded in with a folding axis in the direction perpendicular to the longitudinal direction of the elongated resin film.
