ABSTRACT:
According to this invention, a chip type solid electrolytic capacitor includes a capacitor element, an insulating sheathing resin layer, two anode terminals, and a cathode terminal. The capacitor element is obtained by sequentially forming an oxide film, a solid electrolytic layer, and a cathode conductive layer on an anode body consisting of a valve metal in which anode leads are extracted from two opposite end faces. The insulating sheathing resin layer is coated on an entire outer surface except for both anode lead extraction end faces and a predetermined portion of one surface. The two anode terminals are formed on both the anode lead extraction end faces and peripheral portions thereof. The cathode terminal is formed on the cathode conductive layer exposed from said insulating sheathing resin layer.
