BATTERY UNIT

A battery unit includes at least one battery module, a cooling device configured to deliver a cooling gas configured to cool the battery module to the battery module, and a junction board mounted with a wiring component configured to electrically connect the battery module and an external device and allow a charging power and/or a discharging power of the battery module to flow. The junction board is disposed above the cooling device at a position where at least a part of the junction board overlaps the cooling device when viewed from an upper-lower direction.
