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 filter circuit includes a resonant circuit, and the resonant circuit includes an inductance element and a capacitor. The capacitor includes an element stacked body, an exterior body, a first external electrode and a second external electrode, and a third external electrode. The element stacked body is formed as a stack of a plurality of capacitor elements. In a first capacitor element, a first end portion is electrically connected to the first external electrode. In a second capacitor element, a first end portion is electrically connected to the second external electrode. A third external electrode is electrically connected to a cathode part of the capacitor elements.

Abstract: An electrolytic capacitor includes a capacitor element, an exterior body , a first external electrode, and a second external electrode. The capacitor element includes an anode body that is electrically connected to the first external electrode and has a porous part on a surface thereof, a dielectric layer that is disposed on a surface of at least a part of the porous part, and a solid electrolyte layer that covers at least a part of the dielectric layer, and is electrically connected to the second external electrode. The exterior body has 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. The first external electrode and the second external electrode are disposed along the first principal surface of the exterior body to be separated from each other.
