Patent ID: 7859829

Claim:
An electrolytic capacitor comprising a capacitor element including an anode body having a plurality of pores at a surface, a dielectric film formed at the surface of the anode body, and a cathode body formed on the dielectric film, said cathode body including a conductive solid layer, said conductive solid layer including particles of conductive solid and/or aggregates of said particles, formed using a dispersion including said particles and/or aggregates of said particles and a solvent, and said particles of conductive solid and/or aggregates of said particles in said dispersion having a first particle size distribution peak and a second particle size distribution peak satisfying a relationship of (1): μ 1 >μ 2 (1) where μ 1 and μ 2 represent an average particle size of said first particle size distribution peak and said second particle size distribution peak, respectively, in particle size distribution measurement by a dynamic laser light scattering method.
