Abstract: An electrolytic capacitor production method is performed in the following procedure. An anode body having a dielectric layer is impregnated with a dispersion containing a conductive polymer and a first solvent. Then, a pH of the dispersion with which the anode body has been impregnated is adjusted or a base is added to the dispersion with which the anode body has been impregnated. Then, at least a part of the first solvent is removed from the anode body.

Abstract: An electrolytic capacitor includes a capacitor element, an exterior body that seals the capacitor element, and an external electrode. The capacitor element includes an anode foil, a dielectric layer, and a cathode part. The anode foil includes an anode lead-out part and a cathode forming part. 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.

Abstract: A method for producing an electrolytic capacitor is performed in the following procedure. A solid electrolyte layer including a conductive polymer and a polyhydric alcohol is formed on an anode body on which a dielectric layer is formed. Then, the anode body on which the solid electrolyte layer is formed is impregnated with a first treatment liquid that contains an oxoacid having two or more hydroxy groups.
