METALLIC FOIL JOINING METHOD AND CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a joining structure of a metallic foil, the structure preventing voids or the like from being produced between a weld zone and the metallic foil when the end faces of a plurality of laminated metallic foils are irradiated with a laser beam and joined to each other.

SOLUTION: A metallic foil joining method is disclosed in which the end faces 3a of a plurality of laminated metallic foils 3 are irradiated with a laser beam 4 and joined to each other, wherein the metallic foils 3 are fused by irradiation of the laser beam, and the fused parts 3b is pressurized by a pressing member 5.
