▎ 摘　　要

NOVELTY - A catalyst metal layer (16) on substrate (12) stimulates graphenization. A mask material which masks the side surface of predetermined-shaped catalyst metal layer is formed. A carbon source is supplied to surface of the catalyst metal layer to grow graphene. The graphene is taken out of predetermined shape from catalyst metal layer as graphene raw material (10). USE - Manufacture of graphene raw material used for graphene wiring structure (all claimed) for transistor, fine electrical wiring, bus-bar of lithium secondary battery and harness of motor vehicle. ADVANTAGE - The method efficiently manufactures graphene raw material with excellent peeling resistance with respect to electrode terminal. The graphene wiring structure using graphene raw material has excellent flexibility and high electroconductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene wiring structure, which has insulated resin layer and graphene layer laminated repeatedly, such that insulated resin layer formed in upper and lower sides of each graphene layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining manufacture of graphene raw material. Graphene raw material (10) Substrate (12) Catalyst metal layer (16) Electrodes (18,20)
