▎ 摘　　要

NOVELTY - An electronic device consists of a catalyst metal (3) formed on the substrate (1), with a gap (4), and graphene (5) supported on the catalyst metal. Graphene has a crosslinked structure. USE - Electronic device (claimed). ADVANTAGE - The electronic device has high mobility, property of both metal and semiconductor, simple structure, low driving power and is manufactured easily and reliably. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene, which involves forming graphene on catalyst metal and heat-processing the catalyst metal aggregates in the peripheral portion of the catalytic metal of the predetermined portion. DESCRIPTION OF DRAWING(S) - The drawing shows schematic sectional view of manufacture of graphene.
