Abstract
A solid electrolytic capacitor includes at least one capacitor element, an outer packaging resin, and a coating layer. The at least one capacitor element includes an anode body that includes a dielectric layer, and a solid electrolyte layer that at least partially covers the dielectric layer. The outer packaging resin covers the at least one capacitor element. The coating layer is disposed between the at least one capacitor element and the outer packaging resin. The coating layer contains a fluorine compound.
