Beschreibung
Zusammenfassung:	The present invention provides a solid electrolytic capacitor and a method for producing the same, in which the anode portion is hard to be cut off and the reliability can be improved when the ultrasonic welding is carried out, and in which the volumetric efficiency is improved. The present invention is solid electrolytic capacitor 15, in which capacitor elements 11 are laminated, in which anode portion 5 and cathode portion 4 are electrically connected to anode terminal 17 and cathode terminal 18, respectively, and wherein solid electrolytic capacitor 15 includes outer packaging 10 of an insulating material with which a whole area is covered, as well as in which anode portion 5 includes welded portion 12 at a terminal portion thereof which is connected to anode terminal 17 and includes bundled portion 13 which bundles a part of anode portion 5 between welded portion 12 and insulating portion 3.
