Beschreibung
Zusammenfassung:	Bendability of a copper alloy wire is improved without decrease in an electrical conductivity of the copper alloy wire made of copper alloy containing zirconium. A cable includes: a two-core stranded wire formed by intertwining two electrical wires made of a conductor and an insulating layer covering the conductor; a filler formed around the two-core stranded wire; and a sheath formed around the filler and the electrical wire. The conductor is a copper alloy wire in which a precipitate containing the zirconium disperses, and has a crystal gain diameter that is equal to or smaller than 1 μm, an electrical conductivity that is equal to or higher than 87% IACS, and a tensile stress that is equal to or larger than 545 MPa.
