Abstract
The present invention provides a solid electrolytic multilayer capacitor excellent in yield and capability, and provides a monolayer capacitor element for use in the manufacture of the solid electrolytic multilayer capacitor. In the multilayer solid electrolyte capacitor of the present invention, a solid electrolytic multilayer capacitor 25 in which a plurality of monolayer capacitor elements 7 are stacked such that the anode areas 11 aligned in the same direction are stacked and bonded onto a lead frame 9 on the anode side and the cathode areas are stacked and bonded onto a lead frame 8 on the cathode side so as to have an unfolded fan shape widening toward the distal end of the cathode area from the anode area 11 side, to provide a multilayer capacitor element 19 and the periphery of the multilayer capacitor element 19 that are covered and sealed with an armoring resin 23. The monolayer capacitor element 7 preferably has a constitution such that the end part of the anode substrate 1 having thereon a dielectric oxide layer 2 worked out to an anode area 11, the cathode area 6 is formed by providing a solid electrolyte layer 4 on the dielectric oxide layer 2 in the area exclusive of…
