▎ 摘　　要

NOVELTY - The device comprises a unit for supplying current to a formation area through a contact unit. A storage unit receives a metal catalyst in a roll state. The contact unit contacts a chamber including an influx unit and an exhausting unit. The contact unit comprises a conductive roller positioned in both sides of a formation area, and a pair of brush-type electrodes positioned in both sides of the formation area. The metal catalyst contacts both sides of the electrodes in the formation area. The device further comprises a support roller positioned at a side of the electrodes. USE - The device is useful for producing graphene (claimed). ADVANTAGE - The device is capable of uniformly controls the current flow so that the temperature of the formation area can be uniformly controlled thus producing graphene with high-quality and mass producibility. DETAILED DESCRIPTION - The device comprises a unit for supplying current to a formation area through a contact unit. A storage unit receives a metal catalyst in a roll state. The contact unit contacts a chamber including an influx unit and an exhausting unit. The contact unit comprises a conductive roller positioned in both sides of a formation area, and a pair of brush-type electrodes positioned in both sides of the formation area. The metal catalyst contacts both sides of the electrodes in the formation area. The device further comprises: a support roller positioned at a side of the electrodes; a temperature sensor positioned within the chamber; a control unit for controlling the current supply unit according to a sensing value of the temperature sensor; and a transferring roller arranged in a side among the supply unit, the contact unit and the storage unit. The chamber comprises metal or ceramic material.
