    摘要: In a solid electrolytic capacitor having an electrolyte layer consisting of a solid electrolyte layer and a liquid, the solid electrolytic capacitor, which suppresses a dedoping reaction and which ESR thereof does not keenly increase, in particular, after a loading of heat stress, is provided. In the solid electrolytic capacitor, the electrolyte layer is formed in the capacitor element which is formed by opposing an anode foil and a cathode foil. This electrolyte layer includes the solid electrolyte layer and the liquid. The solid electrolyte layer includes a conductive polymer consisting of a dopant and a conjugated polymer. The liquid is filled in air gaps in the capacitor element on which the solid electrolyte layer is formed. The electrolyte layer includes ammonia as a cation component, and a molecular ratio of the cation component relative to 1 mol of a functional group which can contribute to a doping reaction of the dopant, in the electrolyte layer is 23 or less.

    摘要: 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 on 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.
