A connector pair includes a first connector, and a second connector electrically connected to the first connector. The first connector includes a first electrical contact part provided with a graphene film on a metal base material. The second connector includes a second electrical contact part electrically connected to the first connector via the graphene film. A contact area between the first electrical contact part and the second electrical contact part is smaller than an area of the graphene film coating the metal base material.

Connector and connector pair

A terminal includes a conductor connecting part, a terminal connecting part, and a graphene film. When a first metal material and a third metal material forming a conductor of an electric wire have different ionization tendencies, the graphene film is provided to be arranged between a first surface and the conductor of the electric wire when the conductor of the electric wire is electrically connected to the conductor connecting part. When a second metal material and a fourth metal material forming a surface of an opposite terminal have different ionization tendencies, the graphene film is provided to be arranged between a second surface and the surface of the opposite terminal when the opposite terminal is electrically connected to the terminal connecting part.
