PROBLEM TO BE SOLVED: To provide a battery pack capable of minimizing drop in the pressure for holding batteries, and facilitating size management.SOLUTION: A battery pack 1 includes a case 2 having a plurality of battery housing chambers 20 partitioned by a plurality of partition walls 21 and housing a single cell respectively, battery laminations 30, 31 constituted by connecting a plurality of single cells 300 housed, respectively, in the battery housing chambers 20 and laminated in the thickness direction X so that they can be electrified, and metallic leaf spring members 4 provided in the battery housing chambers 20. Each leaf spring member 4 limits the position of the single cell 300 housed in the battery housing chamber 20 by pressing in the orthogonal direction. |
