Publication number: 20080213589Abstract: An element wire, an electric wire including the element wire or the element wires, and a process for producing an element wire are provided, by which ductility of a core wire consisting of the element wires can be improved. The element wire is made of metal, at least one element wire being coated with an electrically insulating coating so as to constitute an electric wire. The crystal grains constituting the entire element wire are fine isometric grains. In the process for producing the element wire, an electrically conductive material is subjected to drawing so as to reduce a diameter of the material and subsequently subjected to successive bending along a longitudinal direction of the material.Type: ApplicationFiled: February 29, 2008Publication date: September 4, 2008Applicants: Yazaki Corporation, Osaka UniversityInventors: Kenichi Hanazaki, Satoru Yoshinaga, Nobuhiro Tsuji
