Abstract
An electrode foil that progresses an enlargement of the surface area of a dielectric film and that barely causes cracks at the time of winding, a winding capacitor obtained by winding the electrode foil, an electrode foil manufacturing method, and a winding capacitor manufacturing method are provided. An electrode foilis formed of a belt-like foil, and has a surface enlarged parta core partand a plurality of separation partsThe surface enlarged partis formed on the surface of the foil, and the core partis a part remained when excluding the surface enlarged partwithin the foil. The separation partextends on the surface enlarged partdividing the surface enlarged partThe plurality of separation partsshare bending stress when the electrode foilis wound, preventing concentration of stress.
