Abstract
[Object] To provide a method for transferring a graphene film, which can transfer a graphene film on a desired substrate with excellent adhesiveness, can effectively prevent defects from being generated in a graphene film and is excellent also in mass productivity, and a method for manufacturing a transparent conductive film.[Solving Means] One layer or a plurality of layers of graphene films 12 formed on a first substrate 11 and a second substrate 14 are stuck with a resin layer 13 that contains less than 1% by weight of a volatile component and has adhesiveness, the first substrate 11 and the second substrate 14 are pressurized to reduce a thickness of the resin layer 13, the resin layer 13 is cured, after that the first substrate 11 is removed.
