摘要： An electrolytic capacitor includes a cathode body. The cathode body includes a conductive solid layer having particles of conductive solid, formed using a dispersion including particles of conductive solid and a solvent. The particles of the conductive solid in the dispersion have a first particle size distribution peak and a second particle size distribution peak satisfying μ1>μ2, where μ1 and μ2 are the average particle size of the first and second particle size distribution peaks, respectively, in particle size distribution measurement. Accordingly, there is provided an electrolytic capacitor reduced in ESR, and further having high withstand voltage and low leakage current.

摘要： A method of manufacturing an electrolytic capacitor including the following steps as well as an electrolytic capacitor manufactured by the method are provided. The method includes: a dispersion impregnation step of impregnating, with a dispersion containing electrically conductive solid particles or powder and a solvent, a capacitor element having an anode foil with a dielectric coating film formed thereon and an opposite cathode foil that are wound with a separator interposed therebetween; a dry step of evaporating the solvent after the dispersion impregnation step to form an electrically conductive solid layer on a surface of the dielectric coating film; and an electrolytic solution impregnation step of impregnating a gap in the electrically conductive solid layer with an electrolytic solution. Accordingly, an electrolytic capacitor that can be manufactured more easily that is excellent in voltage proofing property and that has a lower ESR and a lower leakage current is provided.
