Abstract
A length of metallic lead from having anode terminals and cathode terminals integrally formed with each other extends between upper and lower molds of an apparatus for manufacturing tantalum solid electrolytic capacitors. The cathode terminals are first coated with a thermosetting conductive adhesive, and cathode layers of capacitor elements are then placed on the conductive adhesive. Thereafter, anode leads extending outwardly from the capacitor elements are placed on the anode terminals are joined thereto, respectively, by welding. A pressure is applied to the capacitor elements so that a portion of the conductive adhesive is squeezed out from one surface of each of the plurality of capacitor elements to a neighboring side surface thereof. The cathode terminals are then joined to the capacitor elements, respectively, by heat-curing the conductive adhesive, and the capacitor elements are finally covered with a sheathing resin.
