It is becoming. Conventionally, as described above, a copper wire coated with an organic insulating material has been used for wiring of audio and visual equipment such as a stereo and a VTR. In such wiring using an organic-coated copper wire, even if a higher-performance sound / image signal is used, the obtained sound quality or image quality is affected by the transmission of the sound / image signal by the wiring, and there is a problem that the quality is not significantly improved. there were.

な本願発明者等の知見に基づくものである。[Effects of the Invention] The high-frequency current transmitting the sound / image signal flows near the surface of the conductor due to the skin effect. Therefore, transmission of the audio / video signal is considered to be very susceptible to the effect of the substance covering the conductor surface. Thus, it has been confirmed by experiments by the present inventors that the higher the hardness of the substance in contact with the conductor surface, the better the transmission of sound and image signals, and the higher the obtained sound quality and image quality. The present invention is based on such findings of the present inventors.

質・画像が得られる。In the case of an organic film conventionally used as an insulator, the hardness of the film can be increased by increasing the temperature at which the organic material is baked on the conductor. However,
When a coating made of ceramics is formed on the conductor surface,
An extremely hard coating is obtained as compared to an organic coating. Therefore, a film made of ceramics is formed on the surface of the conductor. At this time, in order to obtain an insulating effect, the ceramic film may be covered with an insulating material such as an organic material. Alternatively, a ceramic film having a specific resistance of 1 × 10 7 Ωcm or more may be formed. When this ceramic-coated electric wire is used for wiring of an audio / video signal, it exhibits excellent sound / image signal transmissivity as compared with the case of using an organic-coated electric wire, and a good sound quality / image is obtained.

ましい。In addition, as a method of forming a ceramic film on the surface of the conductor, a vacuum deposition method such as a CVD method, a plasma CVD method, or an ion plating method can be adopted. According to the vacuum evaporation method, there is an advantage that a coating film having strong adhesion is obtained with almost no occurrence of pinholes which adversely affect the progress of corrosion. However, if the formed film thickness is less than 0.1 μm, there is almost no effect of increasing the hardness near the conductor surface.
On the other hand, if the film thickness exceeds 30 μm, the above effect is saturated and the time required for forming the film is long. Therefore, it is desirable that the ceramic film has a thickness of 0.1 μm or more and less than 30 μm.

The hardness in the vicinity of the conductor surface, that is, the apparent hardness obtained by adding the hardness of the intermediate layer to the hardness of the ceramics may be increased. A plurality of ceramic coatings may be formed.

The conductor is made by twisting multiple conductor strands together.
A ceramic film may be formed on the surface of each conductor strand.
