PROBLEM TO BE SOLVED: To provide a multilayer solid electrolytic capacitor which can enhance the yield drastically by suppressing increase in leakage current or failure due to short circuit without causing increase in manufacturing cost or enlargement, and to provide its manufacturing process. SOLUTION: A multilayer solid electrolytic capacitor comprises a plurality of capacitor elements 6, each having an aluminum foil 1 provided with an anode 7 and a cathode 8 having a dielectric oxide film 2 and a cathode layer 3 formed sequentially on the surface of the aluminum foil 1. Further, the capacitor is equipped with a cathode structure where the capacitor elements 6 are arranged in multilayer state with the anodes 7 of adjoining capacitor elements 6 being welded, and the adjoining cathodes 8 being connected electrically by a conductive paste layer 18. An insulating resin layer 16 is arranged on the boundary of the cathode 8 and the anode 7 and in the vicinity thereof. COPYRIGHT: (C)2008,JPO&INPIT
