PROBLEM TO BE SOLVED: To suppress temperature rise of a junction box while satisfying demands for eliminating input and output limits and inhibiting the deterioration of the flexibility of a mounting position of a battery pack.SOLUTION: A battery pack includes: an assembled battery formed by laminating multiple electric cells; end plates disposed at end parts of the assembled battery in the lamination direction; and a junction box which houses at least a relay, a bus bar, and a relay terminal and is disposed at a position facing the assembled battery across the end plate. A first rib is formed on a surface of the junction box which faces the end plate, and a second rib is formed on a surface of the end plate which faces the junction box. The first and second ribs are in contact with each other. |
