PROBLEM TO BE SOLVED: To provide a power supply device capable of minimizing a dead space between a case main body and a battery module and preventing lateral shift of the battery module in the case.SOLUTION: A power storage device 1 comprises a battery module 10, and a case main body 3 housing the battery module 10. The battery module 10 comprises: a single battery group 12 having a plurality of stacked battery cells 14; and a battery monitoring unit 80 electrically connected to the single battery group 12. The battery module 10 is housed in the case main body 3 at such an attitude that the battery monitoring unit 80 is arranged along the single battery group 12, seen from an opening 3f of the case main body 3. A dimension of a bottom face part 3a of the case main body 3 is substantially the same as an outer contour dimension of the battery module 10 seen from the opening 3f of the case main body 3. |
