▎ 摘　　要

NOVELTY - The connector pair has a second connector that is electrically connected to a first connector. The first connector is comprised of a first electrical contact unit which is provided with a graphene layer on a metal base material. The second connector is provided with a second electrical contact unit electrically connected to the first connector by the graphene layer. A contact area between the first electrical contact unit and the second electrical contact unit is smaller than an area of the graphene layer which is applied to the metal base material. The metal base material in the first electrical contact unit is comprised of an oxide layer of a metal on the surface. The metal base material is copper and the oxide layer is copper oxide. The graphene layer is reduced graphene oxide. USE - Connector pair for use with electrical device. ADVANTAGE - The connector pair is provided with a low electrical resistance value in which a decrease in conductivity due to oxidation is prevented. DESCRIPTION OF DRAWING(S) - The drawings show a circuit diagram showing a measuring terminal that brought into point contact with electrical contact unit.
