Abstract: A disclosed solid electrolytic capacitor includes: a stacked unit constituted by a stack of a plurality of capacitor units each having a capacitor element including an anode portion and a cathode portion, and a cathode foil connected to the cathode portion via a first conductive paste; and a cathode lead terminal electrically connected to the cathode portion. The cathode lead terminal has at least one side wall portion facing a side surface of the cathode portion and electrically connected to the cathode foil. This makes it possible to reduce the ESR of the solid electrolytic capacitor.

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.
