Patent attributes
A stacked battery includes: a power generation element in which a plurality of electrodes and a plurality of separators are alternately stacked; an exterior member in which the power generation element is accommodated together with an electrolytic solution; and a bonding portion configured to bond an outermost layer of the power generation element and an inner side of the exterior member, wherein when the power generation element is viewed in a plan view from a stacking direction in which the electrodes and the separators are stacked, the bonding portion is located outside an effective region contributing to power generation in the power generation element and has a shape in which an outer peripheral edge of the bonding portion is continuous over an entire circumference of the bonding portion.
