ABSTRACT:
A plurality of anode foils (7) and a plurality of cathode foils (8) respectively having connecting portions (12a,12b) are alternately arranged with insulating separators (9) interposed therebetween. The connecting portions (12a,12b) of the stacked electrode foils (7, 8) are respectively connected and united electrically and mechanically by friction stir welding, thereby forming a capacitor element (5). The capacitor element (5) is housed in a case (2), and the connecting portions (12a,12b) are respectively connected to a positive electrode external terminal (4) and a negative electrode external terminal (4).
