Abstract: Provided is a battery pack capable of accumulating gas released from a battery cell in the battery pack as much as possible while suppressing the other battery cells from becoming hot due to the gas. The battery pack 100 includes a battery module 30, an electrical unit 50, and a housing 70. The housing 70 internally has a first storage space 70a that stores the battery module 30 and a second storage space 70b that stores the electrical unit 50. A part of the housing 70 defining the second storage space 70b includes a duct 80 that communicates the second storage space 70b with an outside of the housing 70.
