Abstract
In an electrolytic capacitor of the present invention, a dielectric layer is provided on a surface of a valve metal element for an anode having a capacitor forming part and an electrode lead part, and further, a solid electrolyte layer and a charge collecting layer for a cathode are provided in this order thereon. The capacitor forming part and the electrode lead part of the valve metal element for an anode have rough surface layers on their surfaces, and are compressed in the thickness direction of the rough surface layers. Further, a region other than the electrode lead part and the charge collecting element for cathode is molded with a molding material. Exposed portions of the electrode lead part and the charge collecting element for cathode function as electrode terminals, respectively.
