Abstract: A solid electrolytic capacitor having high reliability while maintaining suitable electrical characteristics, and a method for producing the same are provided. The solid electrolytic capacitor includes stacked capacitor elements. The capacitor element includes: an anode body; a dielectric layer provided on a surface of the anode body and including a plurality of voids; a solid electrolyte layer provided on a surface of the dielectric layer; a cathode body provided on a surface of the solid electrolyte layer; and an insulating layer that includes an insulating resin insulating and separating between an anode side and a cathode side, the insulating layer being provided on the anode side of the dielectric layer. The plurality of voids included in the insulating layer are filled with the insulating resin. An anode portion adhesive resin is provided between adjacent insulating layers.
