Abstract

A solid electrolytic capacitor includes a capacitor element including a cathode portion and an anode portion, a cathode terminal bonded to the cathode portion, an anode terminal bonded to the anode portion, and an enclosure resin covering the capacitor element. The cathode terminal includes a cathode lower surface portion, a cathode connection portion, and a cathode support portion. The cathode connection portion is connected to an end portion of the cathode lower surface portion on an anode side and bonded to the cathode portion through a conductive adhesive. The cathode support portion is connected to a side portion of the cathode lower surface and brought into contact with a lower surface of the cathode portion on an end portion side of the cathode portion without involving the conductive adhesive therebetween.
