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.
