: A graphene transfe rr ing apparatus comp ri sing: a catalyst metal film, on at least one surface of which a plurality of layers of graphene formed, wherein the catalyst metal film is transported in a predetermined direction; a first unwinding reel which unwinds a substrate film having an adhesive first surface around the first unwinding reel; a first roller that presses the substrate film toward the catalyst metal film so that the adhesive first surface of the substrate film which is unwound from the first unwinding reel is adhered to an outermost layer of the plurality of the layers of graphene; a first winding reel that separates the substrate film from the catalyst metal film that has passed through the first roller and winds the separated substrate film; and a third unwinding reel which unwinds a substrate film having an adhesive first surface around the third unwinding reel; a fifth roller that compresses a third substrate film unwound from the third unwinding reel against the catalyst metal film, from which the substrate film unwound from the first unwinding reel is separated; and a third winding reel that separates the third substrate film from the catalyst metal film that has passed the fifth roller and winds the third substrate film. 2 AMENDMENT UNDER 37 C.F.R. § 1.111 Attorney Docket No.: Q₂₀₄₁₄₃ App l n. No.: 13/988,250
: The graphene transfe rr ing apparatus of claim 9, wherein the plurality of layers of graphene are formed on both surfaces of the catalyst metal film, and wherein the graphene transferring apparatus further comprises: a second unwinding reel which unwinds a substrate film having an adhesive first surface around the second unwinding reel; a second roller that presses the substrate film toward the catalyst metal film so that the adhesive first surface of the substrate film which is unwound from the second unwinding reel is adhered to at least one layer of the plurality of layers of graphene; and a second winding reel that separates the substrate film from the catalyst metal film that has passed the second roller and winds the separated substrate film.
: The graphene transfe rr ing apparatus of claim 9, further comprising a third roller that presses the substrate film between the first roller and the first winding reel toward the catalyst metal film.
