A laminated battery includes an electrode stack including a plurality of electrodes stacked together and having a cuboid shape, and a laminate film covering and sealing the electrodes. The laminate film includes a film body covering four surfaces of the electrode stack, a film partitioning wall interposed between two adjacent electrodes of the plurality of electrodes, and cover members that are twice as many as the electrodes. The film body and the film partitioning wall define accommodating portions respectively accommodating the electrodes. The cover members cover two remaining uncovered sides of each accommodating portion. The cover members each have a recess-shaped portion including a bottom wall and four side walls. An outer surface or an inner surface of the bottom wall faces a side surface of a corresponding one of the electrodes. Outer surfaces of the side walls are fusion-bonded to the film body or the film partitioning wall.
