Beschreibung
Zusammenfassung:	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 foil 1 is formed of a belt-like foil, and has a surface enlarged part 3, a core part 2, and a plurality of separation parts 4. The surface enlarged part 3 is formed on the surface of the foil, and the core part 2 is a part remained when excluding the surface enlarged part 3 within the foil. The separation part 4 extends in a width direction of the belt in the surface enlarged part 3, dividing the surface enlarged part 3. The plurality of separation parts 4 share bending stress when the electrode foil 1 is wound, preventing concentration of stress.
