1 is a copper plate (end electric conductor), 2 is a flexible part formed by stacking a plurality of thin copper plates (thin plate-shaped electric conductor) 2a, and 21 is a weld between the end of the copper plate 1 and the end of the flexible part 2. 31 is a welded part formed at the end of a plurality of thin copper plates 2a to butt-join the end of the copper plate 1 and the end of the flexible part 2; 41 is a welding metal that joins the end of the copper plate 1 and the end of the flexible part 2.
さて、第１図に示した可撓性電気導体を製造する本実施
例の方法について説明する。まず、第２図に示すように
、複数枚の薄板状電気導体２ａの端部を例えばＴＩＧ溶
接により一体化し、フレキシブル部２を形成する。Now, the method of this embodiment for manufacturing the flexible electrical conductor shown in FIG. 1 will be explained. First, as shown in FIG. 2, the ends of a plurality of thin plate electrical conductors 2a are integrated by, for example, TIG welding to form the flexible portion 2.

に示すように、最も単純な■形開先形状の継手（開先部
３１参照）を溶接するものとする。After this, the end of the copper plate 1 and the end of the flexible part 2 are butt welded. At this time, depending on the thickness of the copper plate 1, the end of the copper plate 1 and the end of the flexible part 2 are butt-welded. Various methods can be considered, but in this embodiment, as shown in FIG. 1, a joint with the simplest ■-shaped groove shape (see groove portion 31) is welded.

の熱は下層へ伝わるので、溶融することはない。Here, when directly welding the copper plate 1 and the flexible part 2, the amount of heat input to the thin copper plate 2a at the top becomes large and it melts, making it impossible to join. The thin copper plates 2a may melt. However, as in this embodiment, by first welding the ends of the flexible part 2 and integrating them (-integration), even if the amount of heat input to the uppermost thin copper plate 2a increases, the heat will be transferred to the lower layer. It will not melt because it will not melt.
