To provide a conductor wire further prevented from progress of corrosion, hardly receiving damage and becoming dusty during preservation, hardly affected by the minute surface scratches received at the drawing process of the conductor material, and to provide an excellent insulating wire resistant against corona discharge, hardly generating dielectric breakdown, with a long insulation life, and further provide an electric coil and cable formed by this.

The conductor wire (3) has a semi-conductive layer which is formed by directly coating a semi-conductive paint in which a conductive substance such as carbon black powder is kneaded in an insulating paint, on the outer surface of a conductor, and baking it; and an insulating wire (5) which has formed an insulating layer on the outer surface of this conductor wire.
