ABSTRACT:
A carbon layer is formed on a solid electrolyte layer of the solid electrolytic capacitor, and a conductor layer connected to a cathode terminal is further disposed thereon. The carbon layer contains carbon particles, and a first additive or a second additive. The first additive is formed from at least one of those selected from the group consisting of hydrated silica and silicate. The second additive is formed from at least one of those selected from the group consisting of a condensation product of an aromatic sulfonic acid with formaldehyde, a condensation product of an aromatic sulfonate with formaldehyde, polystyrene sulfonic acid, and polystyrene sulfonate.
