Abstract
A battery pack is a battery pack that is configured by arranging plural chargeable-dischargeable single cells in a specified direction. Each of the plural single cells includes: an electrode body including a positive electrode and a negative electrode; and a box-shaped battery case accommodating the electrode body and an electrolyte. The two adjacent single cells in the battery pack are provided with gas discharge valves in mutually opposing surfaces of the battery cases, each of the gas discharge valves discharging gas that is produced in the battery case. In the battery cases provided in the two adjacent single cells, the gas discharge valves that are provided in the mutually opposing surfaces are disposed at positions that do not overlap each other when seen in an arrangement direction of the single cells.
