    摘要: A solid electrolytic capacitor, including: a solid electrolytic layer; and a dielectric layer on which the solid electrolytic layer is formed. The solid electrolytic layer is formed by applying and drying a conductive-polymer solution including a conductive polymer on the dielectric layer, and the dielectric layer is formed by oxidizing a surface of an anode metal. The conductive polymer has a volume average particle size of smaller than 26 nm. A stacked aluminum electrolytic capacitor including a test solid electrolytic layer and a test dielectric layer, the test solid electrolytic layer being formed by applying and drying the conductive-polymer solution on the test dielectric layer, the test dielectric layer being formed by oxidizing a surface of aluminum having an electrical capacitance of 95 μF/cm2, has a rate of exhibited capacitance of no less than 70%.
