To provide a battery that provides a simple and easy configuration to promote removal of air bubbles occurring in a stacked
electrode body, and thereby improves battery performance. Provided is a battery, which includes a stacked
electrode body formed by stacking a first
electrode plate and a second electrode plate through a separator, an electrolytic solution or an
electrolyte, a battery case that has a first electrode terminal electrically connected to the first electrode plate and a second electrode terminal electrically connected to the second electrode plate and that stores the electrolytic solution or the
electrolyte and the stacked electrode body, and a squeeze section, which is located between the stacked electrode body and the battery case and formed as one body the battery case or separately from the battery case, and in which the thickness thereof is reduced toward each of a plurality of squeeze directions.
