▎ 摘　　要

NOVELTY - The apparatus (10) has a circuit layout portion (100) in which substrate (S) is arranged in one side. A nozzle unit (200) in the form of a pipe is provided with an internal space (210) for a graphite powder (G). A spray hole (200h) is formed on one side of the nozzle unit for spraying the graphite powder onto the substrate through the spray hole. A graphite supply unit (300) is connected to the internal space of the nozzle unit, and provided to supply the graphite powder to the internal space. USE - Graphene flake thin film producing apparatus for producing graphene on substrate using graphite powder. ADVANTAGE - The graphene flake thin film is manufactured at the low cost, and the manufacturing efficiency is improved. The graphene flake thin film is manufactured at room temperature, and the graphene flake thin film is produced regardless of the kind of the substrate material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene flake thin film producing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene flake thin film producing apparatus for producing graphene on substrate using graphite powder.
