Abstract

An electric wire capable of reducing an AC resistance equal to or less than the copper wire. In the electric wire in a single layered structure having a first layer of a substance having lower conductivity than copper, a radius of the wire is less than a skin depth, and an alternating current resistance value of the wire at a frequency used in the wire is greater than or equal to a sum of a direct current resistance value of the wire and a direct current resistance value of a copper wire having a same shape and a same outer diameter as the wire, and less than or equal to an alternating current resistance of the copper wire.
