The oil-tempered wire has a tempered martensite structure. A lattice constant of a nitride layer formed on a surface of the wire is 2.870 Å to 2.890 Å when the oil-tempered wire is nitrided. The oil-tempered wire is produced by wire drawing a steel wire and quenching and tempering the wire drawn steel wire. The quenching is performed after the radiation heating is performed at 850 to 950° C. for over 30 sec to 150 sec, and the tempering is performed at 400 to 600° C.

摘要： There are provided a lightweight insulated electric wire capable of reducing influences of external magnetic fields while having an excellent conductivity and an excellent strength and an automobile wire harness using the same insulated electric wire. There is provided a signal electric wire including a conductor portion consisting of one or more first wires and one or more second wires, which are stranded together. The first wires are constituted by metal wires made from at least one type of metal selected from a group consisting of copper, copper alloy, aluminum and aluminum alloy. The second wires are constituted by metal wires different from the first wires and have a relative permeability of 4.0 or less. By setting the relative permeability of the constituent wires of the conductor portion to 4.0 or less, it is possible to suppress temperature rises caused by eddy current loses due to external magnetic fields, thus alleviating degradation of the insulation layer and poor insulation.
