Abstract: An object of exemplary embodiments is to prevent increasing the height of a battery module housing a battery pack and a junction box. In the junction box, resin cases of a high-profile relay and an electric component are fixed to the shielding case wall. A low-voltage electric wire or a high-voltage electric wire is laid out on the metal plate. A resin case cover is put on when the relay and electric component is fixed to the bottom wall or the metal plate. The low-voltage electric wire or the high-voltage electric wire is covered with the case cover, predetermined contact portions of the relay and the electric component are exposed, the low-voltage electric wire or the high-voltage electric wire and a bus bar are disposed on the case cover, and the bus bar, the low-voltage electric wire or the high-voltage electric wire are connected to the exposed contact portions.
