Abstract
A solid electrolytic capacitor according to the present disclosure includes an anode body made of a porous valve metal, a dielectric layer formed on a surface of the anode body, and a solid electrolyte layer formed on the dielectric layer. A carboxylic acid ester is filled in at least part of cavities inside the solid electrolyte layer. By the solid electrolytic capacitor according to the present disclosure, it is possible to provide a solid electrolytic capacitor capable of suppressing an increase in ESR and an increase in leakage current.
