▎ 摘　　要

NOVELTY - The conductor (10) has a graphene coating layer (20) that is coated on the surface of the conductor, such that the graphene layers contained in the graphene coating layer have hexagonal lattice form of carbon atoms. The ratio of an area of a lattice defect to a total area of each of the graphene layers is calculated and a calculated defect rate is 30% or less. The conductor has copper, copper alloy, aluminum, aluminum alloy, copper plated with different metal, copper alloy, aluminum and an aluminum alloy. The dissimilar metal has nickel, iron, cobalt, ruthenium, rhodium, lead or iridium. USE - Composite conductor comprising graphene coating layer used in wire (claimed). ADVANTAGE - The electric wire including the composite conductor exhibits an effect of lower manufacturing cost and excellent workability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a wire. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-section of the composite conductor comprising graphene coating layer.
