description A method for manufacturing an energy storage device includes a swaging step in which a swaged portion is formed by swaging a tip portion, penetrating a positive electrode terminal or a positive electrode current collector and projecting in a predetermined direction from the positive electrode terminal or the positive electrode current collector, of a shaft portion. In the swaging step, the tip portion of the shaft portion is swaged by a punch which includes a pressing surface, the pressing surface including a punch-side first concave portion which is concaved in the predetermined direction and a punch-side second concave portion which is concaved in the predetermined direction more than the punch-side first concave portion at an inner peripheral side of the punch-side first concave portion.
