Abstract
A simple method of mass producing a plurality of solid electrolytic capacitor elopements can be performed to produce capacitors with reduced leakage current and excellent reliability. The method includes supplying a band metal, a first portion of which contains protrusions on which a dielectric layer, then a conductor layer are formed. A conductive polymer film is formed on the conductor layer by electrolytic polymerization starting from a conductive tape adhered on a second portion of the band metal. The conductive tape acts as a common positive electrode for polymerization and a plurality of electrodes connected independently to the protrusions as negative electrodes. Finally a plurality of capacitor elements are formed by laminating individual protrusions cut off from the band metal.
