である。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is applicable to, for example, TV+CRT (Cathode
The present invention relates to conductors used in the wiring of image display devices such as ray tubes (ray tubes), and devices that require high-frequency signal transmission circuits, such as audio devices and other audio devices.
（背景技術）
これらの電子機器は、信号が正確に、位相差を生じるこ
となく伝達されないと、画像や音響において像がぼやけ
たり、音が鮮明でなかったりする。(Background Art) In these electronic devices, if signals are not transmitted accurately without creating a phase difference, the image or sound may become blurred or the sound may not be clear.
従来、タフピッチ鋼（酸素２００〜５００ＰＰｍ程度含
存する純銅）や無酸素鋼（酸素をほとんど含まない純銅
）を冷間加工後焼鈍軟化して再結晶させた軟銅線や、時
として冷間加工したままの硬銅線、又はこれらに錫等の
めっきを施した線がこれらの用途に使用されてきた。Conventionally, annealed copper wires are produced by cold-working tough pitch steel (pure copper containing about 200 to 500 PPm of oxygen) or oxygen-free steel (pure copper containing almost no oxygen), annealing and recrystallizing it after cold working, or sometimes leaving it cold-worked. Hard copper wires or wires plated with tin or the like have been used for these purposes.
しかし、これらの線は次の理由により必ずしも信号の正
確な伝達に好都合なものではなかった。However, these lines are not always convenient for accurate signal transmission for the following reasons.
軟銅線は、しなやかさが優れるので、多用されるが、焼

分信号にとって位相−差発生等の原因として太き（作動
すると考えられる。Annealed copper wire is often used because it has excellent flexibility, but when recrystallized by annealing, the crystal grains are usually distributed in an almost equiaxed shape, so when a current flows in the longitudinal direction of the conductor, the crystal grains that would cross The number of fields increases, and the grain boundaries are considered to be thick (operating) as a cause of phase difference generation, etc., especially for high frequency component signals.
硬銅線の場合、軟鋼線に比べて繊維状に長子方向に伸び

際、横切るであろう結晶粒界は見掛は上少ない点より、

端に多く、電気伝導に不適当な電子密度の不均質などが
多く、これも高周波成分信号にとって位相差発生の原因
となると考えられる。In the case of hard copper wire, compared to mild steel wire, it has a fibrous crystal shape that extends in the longitudinal direction, so when a current flows in the longitudinal direction, there are apparently fewer grain boundaries to cross. Than,
Although it is less susceptible to the negative effects of grain boundaries, atomic vacancies (point defects)
, the density of dislocations (linear crystal defects) is extremely high compared to mild steel wire, and there are many inhomogeneities in electron density that are inappropriate for electrical conduction, and this also causes a phase difference for high-frequency component signals. Conceivable.

が結晶の電子構造と乱れをつくり易く、これが高周波信
号の乱れ、位相差を生じる原因となる恐れがある。In the present invention, the purity of copper or copper is preferably 99.99% or more. When the purity of 9L is less than 93%, the presence of impurity atoms tends to create disturbances in the electronic structure of the crystal, which may cause disturbances in high frequency signals and phase differences.

響機器では、澄んだ透明感のある鮮明な音響となる。(a) Because it is made of copper or a linear body of copper consisting of a collection of structures that are considered to be substantially single crystal over a length more than twice the diameter, there are few grain boundaries that cross the longitudinal direction, and the crystals are aligned. Since there are few parts with large disturbances, there is no signal disturbance or phase difference in the image and sound signal currents flowing through the conductor, so image display equipment can display whites more clearly (and colors). The image becomes brighter and the image becomes clearer.Also, in the case of audio equipment, the sound becomes clear and transparent.
