摘要：An electrolytic capacitor includes a capacitor element and an electrolyte

solution impregnated in the capacitor element. The capacitor element includes an anodefoil, cathode foil, separator, and a solid electrolytic layer. The anode foil has a dielectriclayer on its surface, and the cathode foil confronts the anode foil. The separator isinterposed between the anode foil and the cathode foil. The solid electrolytic layer isformed on the surfaces of the anode foil, cathode foil, and separator as an aggregate offine particles of conductive polymer. The separator has an air-tightness not greater than2.0 s/100 ml. Sizes of the fine particles measure not greater than 100 nm in diameter, andan amount of the fine particles contained falls within a range from 0.3 mg/cmto 1.2mg/cm, inclusive, as converted to weight per unit area of the anode foil.
