Abstract
There are provided a transparent conductive film, as well as a heater, a touch panel, a solar battery, an organic EL device, a liquid crystal device, and an electronic paper that are provided with the transparent conductive film, the transparent conductive film being capable of easing a decline in optical transmittance when graphene is laminated, and of achieving optical transmittance higher than an upper limit of optical transmittance of a single layer of graphene. The transparent conductive film includes a single-layered conductive graphene sheet. The single-layered conductive graphene sheet includes a first region and a second region, the first region being configured of graphene, and the second region being surrounded by the first region and having optical transmittance that is higher than optical transmittance of the first region.
