In a battery pack, battery pack flange portions (11a) are provided at opposing sides of a battery assembly (10A) along a stacking direction of battery modules (11A), so as to project laterally. The battery module flange portions (11a) are interposed between an upper case flange portion (3 a) and a lower case flange portion (4a) when the upper case flange portion (3 a) and the lower case flange portion (4a) are overlaid, and fastened and fixed concurrently by bolts (33). The bolts (33) are also used in fixing the battery pack (1A) to a vehicle (100). With this configuration, a battery pack that can reduce assembly steps with the bolts and the like to improve efficiency in the fastening work can be provided. |
