Abstract:
The present invention relates to a method of manufacturing an electrode lead including: arranging a plurality of lead pieces between a first lead film and a second lead film in a length direction of a lead film including the first lead film and the second lead film; first sealing the first lead film and the second lead film; bending the lead film to form a lead piece laminate in which the plurality of lead pieces are stacked in a height direction with respect to a plane of the lead film; and second sealing the bent lead film overlapping the plurality of lead pieces.
