Abstract: Provided is a battery pack (10) the reliability of which can be enhanced. This battery pack (10) accommodates a secondary battery (14) inside a case (12). The battery pack includes: an exhaust port (22) that provides communication between an internal space of the case (12) for accommodating the secondary battery (14) and the outside and that discharges gas discharged from the secondary battery (14) from the inner space to the outside; and a heat exchange body (24) that is provided to the exhaust port (22) and is formed of a porous material having a three-dimensional mesh structure so that gas passes therethrough.
