1. A transparent conducting film laminate comprising a carrier film and a transparent conducting film stacked on the carrier film, wherein
the carrier film comprises a protection film which is provided, on one of the main faces thereof, with an adhesive agent layer,
the transparent conducting film comprises a transparent resin film which is provided, on one or both of the main faces thereof, with a transparent conducting layer containing metal nanowires and a binder resin, and an overcoat layer stacked in this order,
the transparent resin film is made of an amorphous cycloolefin-based resin, and has a thickness T1 of 5 to 25 μm,
the transparent conducting film laminate is constituted by providing the transparent conducting film to be releasably stacked on the adhesive agent layer of the carrier film so that the overcoat layer becomes the outermost layer,
the protection film is made of polyester having an aromatic ring in its molecular backbone, and
the protection film has a thickness T2 which is 5 times or more of the thickness T1 of the transparent resin film, and is 150 μm or less.
