ELECTRONIC WIRE AND METHOD OF MANUFACTURING THE SAME

摘要

To provide an electronic wire having a diameter reduced while ensuring an excellent abrasion resistance and a method of manufacturing the electronic wire. An electronic wire 1 is obtained by coaxially providing sequentially a central conductor 2, an insulator 4, an outer conductor 6 and a jacket 7. The central conductor 2 consists of twisted copper alloy wires 3 each containing silver in an amount which is equal to or larger than 1 weight % and is equal to or smaller than 3 weight % and each having a diameter which is equal to or larger than 0.010 mm and is equal to or smaller than 0.025 mm, and a tensile strength of the central conductor is equal to or higher than 950 MPa and a conductivity of the central conductor is equal to or higher than 70% IACS and is equal to or lower than 85% IACS. The jacket 7 is formed of ETFE having a melt flow rate which is equal to or higher than 25 and is equal to or lower than 45, and has a thickness which is equal to or greater than 10μm and is equal to or smaller than 30μm, and has an outside diameter which is equal to or smaller than 0.35 mm.
