Beschreibung
Zusammenfassung:	To provide a technique which can surely make a surface of a bare conductive wire hydrophilic to form a thin insulative coat having high density.SOLUTION: A technique disclosed by the specification is embodied into a production method of a coil wire. The production method includes: a formation step in which irregularities are formed on a surface of a bare conductive wire; and an application step in which an insulation material is applied to the surface of the bare conductive wire formed with the irregularities to form an insulative coat. In the formation step, a plurality of protruding parts are formed in a matrix shape and a diameter of each protruding part is 10 micrometer or smaller.SELECTED DRAWING: Figure 3 【課題】裸導線の表面を確実に親水化して高密度な薄厚の絶縁被膜を形成することができる技術を提供する。【解決手段】本明細書が開示する技術は、コイル線の製造方法に具現化される。この製造方法は、裸導線の表面に凹凸を形成する形成工程と、凹凸が形成された裸導線の表面に、絶縁材料を塗布して絶縁被膜を形成する塗布工程と、を備える。形成工程では、複数の凸部がマトリクス状に形成されるとともに、各々の凸部の直径は１０マイクロメートル以下である。【選択図】図３
