DETAILED DESCRIPTION - Graphene film manufacturing device comprises wrinkles flattening device for flattening the folds of the base substrate and stacked structure which includes a graphene film which is stacked on the base substrate. The first substrate is laminated on the graphene film by first laminating equipment. The laminating equipment includes a lamination roller which is facing the corrugation planarization device. The supporting roller is connected to the lamination roller and supports the lower surface of the pleated flattening device. The lamination roller and the wrinkle flattening device is movably provided and the wrinkle flattening device comprises a porous adsorption member (110) which is provided to vacuum-adsorb the base substrate in contact with the base substrate. The support member supports porous adsorption member. The hollow space (115) is provided between the porous adsorption member and the support member. The vacuum suction port (121) is communicated with the hollow space in the support member and the vacuum suction port is formed on the side surface of the graphene film manufacturing device. An INDEPENDENT CLAIM is included for method for preparing graphene film which involves: (A) laminating the first substrate on the graphene film; (B) planarizing the wrinkles of laminated graphene film; (C) performing vacuum-absorption on the base material by using the porous absorption member which is contacting with the base material; (D) flattening the corrugation of laminated structure; and (E) laminating the first substrate by a continuous process or a simultaneous process.
