ABSTRACT:
It is an object of the present invention to provide a solid electrolytic capacitor which can reduce the ESL and the ESR and increase electrostatic capacitance at a small size, and a method for manufacturing such a solid electrolytic capacitor. A solid electrolytic capacitor component includes a foil-like aluminum substrate whose surface is roughened or enlarged and which is formed with an aluminum oxide film2xon the surface thereof and foil-like aluminum substrates whose surfaces are not roughened and a cathode electrode including a solid high molecular polymer electrolyte layer, a graphite paste layer and a silver paste layer is formed on the surface of the foil-like aluminum substrate. In the solid electrolytic capacitor component110, lead electrode pairs including anode lead electrodes are disposed adjacent with each other, whereby magnetic fields to be generated are canceled.
