Abstract
An electrolytic capacitor includes a capacitor element including a porous anode body, an anode wire partially embedded in the anode body, a dielectric layer formed on a surface of the anode body, and a solid electrolyte layer covering at least a portion of the dielectric layer, wherein the anode body is formed of a first metal, the anode wire is formed of a second metal having a different composition from the first metal, and the second metal has a conductivity S2 that is larger than a conductivity S1 of the first metal. This allows for providing an electrolytic capacitor which suppresses an increase in production costs and has a low ESR.
