Abstract

A battery pack has a plurality of unit cells, a casing for accommodating the plurality of unit cells, and a base which is a part of the casing and has a heat dissipation wall and a first side wall disposed so as to be capable of transferring heat to the heat dissipation wall. The battery pack includes a stay disposed on the first side wall in the base and fixed to a vehicle-side member, and a switching device disposed so that released heat can be transferred to the heat dissipation wall or the first side wall. The switching device includes a first switching device and a third switching device having a smaller heating value than the first switching device has. The first switching device is disposed at a position closer to the stay than the third switching device is in planar view.
