Abstract

A high-frequency electric wire is provided with a conductor which formed by compressing multiple wire strands, each of which is obtained by coating an outside of a wire rod made of insulating resin with a metal layer, and a sheath provided on the conductor. Each of the wire strands of the conductor is compressed in such a way that a deformation ratio of the wire strand exceeds 0% and is 20% or less. The compression is performed, for example, during bundling and sheathing of the multiple wire strands.

Claims

1. A high-frequency electric wire comprising:

a conductor in which a plurality of wire strands are compressed, each of the wire strands including a wire rod made of electrically insulating resin and a metal layer coating an outer circumference of the wire rod; and

a sheath provided on the conductor,

wherein the each of the wire strands of the conductor is compressed so that a deformation ratio of the each of the wire strands exceeds 0% and is 20% or less.

3. A wire harness comprising the high-frequency electric wire according to claim 1.

2. A method of manufacturing a high-frequency electric wire comprising:

obtaining a plurality of wire strands, each of the wire strands including a wire rod made of electrically insulating resin and a metal layer coating an outer circumference of the wire rod, by coating an outer circumference of each of the wire rods with the metal layer; and

compressing the plurality of wire strands by bundling and sheathing,

wherein the each of the wire strands is compressed in such a way that a deformation ratio of the each of the wire strands exceeds 0% and is 20% or less.
