Abstract
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 μ>μ, where μand μare 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.
