To provide a segment coil split conductor which enables edges of split conductors to be easily welded and can be easily handled and to provide a manufacturing method for the segment coil split conductor.SOLUTION: A split conductor 5 has a split section 8 made up of a plurality of wire sections 7 at a portion other than both edge sections 9. Each wire section 7 has a conductor section 11 and an insulation layer 13 which covers the conductor section 11. That is, the split section 8 is made up of the plurality of conductor sections 11 and the insulation layers 13 formed between the conductor sections 11. Both edge sections 9 of the split conductor 5 are integrated with the conductor sections 11. That is, at least both edge sections 9 of the split conductor 5 are not provided with the insulation layer 13 so that the conductor section 11 is exposed without being split into plural pieces.SELECTED DRAWING: Figure 3 【課題】 分割導体の端部同士を容易に溶接することが可能であり、取扱いが容易なセグメントコイル用分割導体及びその製造方法を提供する。【解決手段】 分割導体５は、両方の端部９以外の部位に、複数の素線部７からなる分割部８を有する。素線部７は、それぞれ、導体部１１と、導体部１１を被覆する絶縁層１３とを有する。すなわち、分割部８は、複数の導体部１１とそれぞれの導体部１１同士の間に形成される絶縁層１３とからなる。分割導体５の両方の端部９は、導体部１１が一体化されている。すなわち、分割導体５の少なくとも両方の端部９においては、絶縁層１３が形成されておらず、導体部１１が複数に分割されずに導体部１１が露出する。【選択図】図３
