０４号公報）。(Prior art) Some audio wires use oxygen-free copper wires, which are made by heating oxygen-free copper wires with an oxygen content of 5 Qppm or less in an inert gas atmosphere at 700'C or more.
It is an electric wire made by drawing an oxygen-free copper conductor obtained by enlarging crystal grains to make it thinner (for example, Japanese Patent Application Laid-Open No. 59-1679
Publication No. 04).
（発明が解決しようとする問題点）
オーディオ機器の配線材として無酸素銅線を使用すると
、タフピッチ銅課を使用した場合より音質が著しく改善
されることは知られているが、該無酸素銅線は音楽信号
に対して高域の音のぬけおよび音色が不十分であるとい
う評価がある。(Problem to be Solved by the Invention) It is known that when oxygen-free copper wire is used as a wiring material for audio equipment, the sound quality is significantly improved compared to when tough pitch copper wire is used. Lines have been evaluated as having insufficient high-frequency sound clarity and timbre compared to music signals.
（問題点を解決するための手段）
発明者はより高度の高質を得るために電線を改良すべく

（ノイズ）ｆニー様に軽減させる。(Means for Solving the Problems) The inventor has completed the present invention as a result of various studies and studies aimed at improving electric wires in order to obtain higher quality wires. That is, the present invention is an audio wire made of oxygen-free copper (purity of 99.95% or more) with a crystal grain size of 5 μm or less. To reduce noise that is likely to occur in a wide frequency band.
（作用） 上記手段は次のように作用する。(effect) The above means works as follows.
信号伝送時に蓋然的に発生する雑音（ノイズ）が−様に
軽減さ詐ることによって、高域の音のぬけおよび音色が

A signal of 630 Q) Iz was input to the oxygen-free copper wire of the present invention and a comparative oxygen-free copper wire with a crystal grain size of 20 μm, and the amount of noise in the output signal was investigated. The measurement results are shown in FIGS. 1 and 2, with FIG. 1 showing the oxygen-free copper wire of the present invention and FIG. 2 showing the comparative oxygen-free copper wire. It can be seen that the oxygen-free copper wire of the present invention has extremely low noise in the output signal compared to the comparative oxygen-free copper wire. When listening to stereo playback sound using the thus obtained wire as an audio signal line, it was found that there was no comparison. Compared to oxygenated copper wires, the clarity and timbre of high-frequency sounds are much better, the rise is significantly better, and interference between noises is extremely reduced, making it easier to separate and localize musical tones. It was extremely good.
