この発明は、小型高周波コイル用巻線や極細リード線な

使われてきている。BACKGROUND OF THE INVENTION Conventionally, ultrafine insulated wires with a finished diameter of 100t and 1z or less have been used as winding wires for small coils and wiring materials for electronic devices.
ところが、最近これら機器の極小型化、高密度実装化に
ともない、さらに細径の、例えば５０μｌ以下の極細絶
縁電線が要求されている。However, recently, with the miniaturization and high-density packaging of these devices, there is a demand for ultra-thin insulated wires with even smaller diameters, for example, 50 μl or less.

、絶縁電線自体の破断引張荷重は小さくなるため、アセ
ンブリ時に作用する張力でしばしば断線することがある
。また、破断に至らなくとも張力により弾性限界を越え
、絶縁電線が伸びてしまうこともある。However, as the diameter of the insulated wire becomes smaller, the breaking tensile load of the insulated wire itself becomes smaller, so that the wire often breaks due to the tension applied during assembly. Furthermore, even if the wire does not break, the tension may exceed its elastic limit and the insulated wire may stretch.
このような欠点を解決するために、引張強さが高い銅合
金、例えば銅−銀合金を導体とすることが考えられてい
るが、これによっても破断引張荷重が高々３０％増加す
る程度であって、十分高い引張強さを得るに至っていな
い。In order to solve these drawbacks, it has been considered to use a copper alloy with high tensile strength, such as a copper-silver alloy, as a conductor, but this would only increase the breaking tensile load by at most 30%. Therefore, it has not been possible to obtain sufficiently high tensile strength.
よって、この発明における課題は、径が極細であるにも
かかわらず、高い破断引張荷重を有する絶縁電線を得る
ことにある。Therefore, an object of the present invention is to obtain an insulated wire that has a high breaking tensile load despite having an extremely small diameter.
