摘要： A solid electrolytic capacitor that includes a cathode foil and solid electrolyte made of conductive polymer. This cathode foil is made by providing a nickel layer on a surface of a base material made of valve metal. This nickel layer includes a layer containing only nickel and a layer containing nickel oxide. Both large capacitance and low equivalent series resistance are achievable at the same time with this simple structure at low cost.

摘要： A solid electrolytic capacitor has a capacitor element and a conductive polymer as a solid electrolyte. The capacitor element includes an anode foil having a dielectric oxide film thereon, a cathode foil, and a separator interposed between the anode and cathode foils, which are wound so as to form a capacitor element. The conductive polymer is disposed between the anode and cathode foils and formed by chemical polymerization of a polymerizable monomer. The separator is made of a nonwoven fabric of synthetic fiber and has an affinity to the polymerizable monomer. The separator includes main fibers and binder fibers each having a fiber diameter smaller than that of each of the main fibers and allowing the main fibers to be bonded together.

For this purpose, the aluminum electrolytic capacitor includes a capacitor element having a positive electrode foil, a first separator, a negative electrode foil, and a second separator, which are sequentially laminated one on another and wound together. After the capacitor element is impregnated with a driving electrolyte solution and housed in a metallic case, an open end of the metallic case is sealed with a sealing material. A ratio of B/A, i.e. a ratio of total thickness B of the first and second separators after winding with respect to total thickness A of the first and second separators before winding, is set in the range from 0.5 to 0.8.
