PROBLEM TO BE SOLVED: To provide a battery pack which can efficiently adjust temperature of a secondary battery while partitioning a flow path by using a case in which the secondary battery is accommodated.SOLUTION: A battery pack 10 includes a square-box like case 11. Battery modules 21, 22 are accommodated in the case 11. The battery modules 21, 22 are arranged so as to abut on adjacent square batteries 23 and include spacers forming flow paths for temperature adjustment. Inflow paths 31 and outflow paths 32 are partitioned between: side faces in a square battery width direction, of the square batteries 23; and inner faces of the case 11 facing these side faces. Heat conducting sheets 33 are provided between: terminal faces 23a on which terminals 26 of the square batteries 23 are projectingly provided; and the inner faces of the case 11. |
