Zusammenfassung:PROBLEM TO BE SOLVED: To enhance connection strength of an electrode foil and a lead-out terminal, by preventing damage on the electrode foil, e.g., cracking or foil break incident to pressure-welding connection.SOLUTION: In a capacitor where a lead-out terminal (4) is connected to an electrode foil (2) by cold-welding, a recess (8) formed in the electrode foil (2) and the connection thereto by cold-welding has a circular planar shape. A manufacturing method therefor is also provided. Since the pressing surface of a cold-welding mold does not have a corner, local stress concentration on the electrode foil can be avoided.
