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.
