Solid electrolytic capacitor and method for producing the same

A method for producing a solid electrolytic capacitor, comprising the steps of:

• providing an anode part at one end of an anode substrate composed of a valve-acting metal having on the surface thereof a dielectric film layer,
• forming a notched part in the valve-acting metal in a remaining portion of the anode substrate other than the anode part;
• forming a solid electrolyte layer on the dielectric film layer of the valve-acting metal in the remaining portion of the anode substrate,
• forming an electrically conducting layer on the solid electrolyte layer to prepare a solid electrolytic capacitor element having a cathode part,
• stacking a plurality of the solid electrolytic capacitor elements wherein the notched parts are superposed one on another,
• at least partially filling an electrically conducting material in the notched parts,
• connecting the cathode parts and the anode parts to a lead frame, and
• molding the stacked body with an outer jacket resin.
