The anode lead-out part has a first end of the anode foil. The cathode forming part has a second end of the anode foil. The dielectric layer is disposed on a surface of the cathode forming part. The cathode part covers at least part of the dielectric layer. The first end in the anode lead-out part protrudes from an end surface of the exterior body. At least part of the first end is in contact with the external electrode.
