Abstract: An electrolytic capacitor includes exterior body and an element stack body including a plurality of capacitor elements. Each of the plurality of capacitor elements includes an anode body, a dielectric layer, and a cathode part covering at least a part of the dielectric layer. The exterior body includes a first principal surface, a second principal surface intersecting the first principal surface, a third principal surface opposite to the first principal surface, and a fourth principal surface opposite to the second principal surface. In at least one first capacitor element among the plurality of capacitor elements, an end surface of an end of the anode body is exposed from the exterior body at least on first principal surface to be electrically connected to a first external electrode. And an end surface of an end of the cathode part is exposed from the exterior body at least on second principal surface to be electrically connected to a second external electrode.

Abstract: A solid electrolytic capacitor includes a capacitor element, an anode terminal, a cathode terminal, and an outer package. The capacitor element includes an anode part, a dielectric body formed on a surface of the anode part, and a cathode part containing a conductive polymer. The anode terminal is electrically connected to the anode part. The cathode terminal is electrically connected to the cathode part. The outer package houses the capacitor element while exposing a part of the anode terminal and a part of the cathode terminal. The solid electrolytic capacitor includes a communicating path that connects a surface of the capacitor element to an exterior of the outer package.

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.
