できる。Since the barrier layer is provided on the conductor of copper-based metal material, it becomes an alumite layer. There is no possibility that one layer will diffuse into the conductor during manufacturing and cause the conductor to deteriorate, and since the insulating layer has a two-layer structure of an alumite layer and a ceramic layer, each layer can be made thinner. A dense layer is obtained, and the sealing treatment prevents cracks from occurring due to bending, etc. Further, among the constituent materials, the one having the lowest melting point is a copper-based material that serves as a conductor, and therefore, the heat-resistant electric wire of the present invention can be used up to temperatures close to the melting point of copper. Furthermore, since the conductor of the size used is coated with a barrier layer and an insulating layer, thin wires and the like can be easily manufactured.

第１表に示した。1. Regarding each of the heat-resistant wires thus obtained and the conventional alumite wire (Comparative Example 3). Except for the heat-resistant wire of Example 3, the wires were wound into coils around a 50-diameter rod to examine the withstand voltage characteristics. Heat resistance is 700 for the above coil-wound product.
After repeating the cycle of heating with CI H and cooling to room temperature 100 times, the withstand voltage characteristics were measured and evaluated. The withstand voltage characteristics were measured according to the JI33003 metal foil method. The results are shown in Table 1.
第１表より明らかなように、本発明品（１〜３）は、い
ずれもｉ４’ｆｆｌ圧特性に優れている。As is clear from Table 1, the products of the present invention (1 to 3) are all excellent in i4'ffl pressure characteristics.
コイル巻き後の耐電圧は、Ｎｏ３が最も高いが、これは
コイル巻き後に陽極酸化及び封孔処理を施したので絶縁
層にクラックが全く存在しなかった為である。The withstand voltage after coil winding was the highest in No. 3, but this was because no cracks existed in the insulating layer because anodizing and sealing were performed after coil winding.
耐熱試験後Ｎｏｌ、３の耐電圧が低ドしているのは、熱

層の熱膨張率がほぼ同し値となり各層の密着性が良好に
保たれた。The reason why the withstand voltage of No. 3 was low after the heat resistance test was because some cracks were generated at the interfaces of each layer due to the difference in thermal expansion. In No. 2, since a Cu-W based composite material was used for the conductor, the coefficient of thermal expansion of each layer was approximately the same value, and the adhesion of each layer was maintained well.

縁層が薄い為であり、Ｎｏ５は絶縁層は厚いが、ポーラ

た為である。On the other hand, the comparative products (4 to 6) already have low withstand voltage after coil winding. This is because No. 4.6 has a thin insulating layer, and No. 5 has a thick insulating layer but is porous, and furthermore, the insulating layer is cranked during coil winding.
加熱試験後は、Ｎｏ４．６は、１１層が溶融してしまっ
た為、又Ｎｏ５は熱膨張差により各層界面に亀裂が生し
いずれも低い値となった。After the heating test, No. 4.6 had 11 layers melted, and No. 5 had cracks at the interfaces of each layer due to the difference in thermal expansion, resulting in both low values.

。Although an embodiment in which the wire is applied to a magnet coil has been described above, it has been demonstrated that the heat-resistant wire of the present invention can also be sufficiently used for power distribution lines such as high-rise buildings where fire resistance is required.
