Abstract
A bipolar battery (2) is constructed by laminating a plurality of bipolar electrodes (3), each constituted by a layer-form collector (4), a positive electrode active material layer (5) disposed on one surface of the collector (4), and a negative electrode active material layer (6) disposed on another surface of the collector (4), via an electrolyte layer (7). A voltage detection terminal (21a, 21b) is attached to a peripheral edge portion of the collector (4). By disposing a voltage detection terminal (21b) of an adjacent collector (4) on an opposite side of a second straight line (Da2), which passes through a centroid (O) of the collector (4) and is orthogonal to a first straight line (Da1) that connects the voltage detection terminal (21a) to the centroid (O) of the collector (4), a state of charge within an identical unit cell (15) is made even.
