Abstract
The method for manufacturing a laminated metal foil () according to the present invention includes: a first step of forming, in a weld site (A) of laminated layers of a metal foil (), by the use of a cutter (C) whose longitudinal cross-sectional shape is a substantially V-shape, a notch () that is linear in a planar view and penetrates the laminated layers of the metal foil () in a lamination direction (S), to cause the laminated layers of the metal foil () to bond to each other along the lamination direction (S) at ends () of a linear notch; and a second step of bringing an electrode (E) for resistance welding into press-contact with the weld site (A) and then energizing the weld site (A) via the electrode (E), to perform resistance welding on the laminated metal foil ().
