Abstract:
An electrolytic capacitor including: an element stack including a plurality of capacitor elements; a package body sealing the element stack; and a first and second external electrode. Each of the capacitor elements includes a first end at which the anode body is exposed, and a second end covered with the cathode section, with at least an end surface of the first end exposed from the package body. The capacitor elements include a first capacitor element in which the first end faces a first surface of the package body, and a second capacitor element in which the first end faces a second surface different from the first surface of the package body. The first and second capacitor elements stacked alternately. The first end of the first capacitor element and the first end of the second capacitor element are electrically connected to the first external electrode and the second external electrode, respectively.
