A battery pack constituted by accommodating a plurality of cells, which forms battery modules, in an internal space of a casing includes the cells, a heat radiating bus bar, the casing, and an internal blower. The plurality of cells is arranged side by side facing each other. A radiation bus bar radiates heat into the internal space from the cells. The casing has a box-like shape with at least six surfaces that surrounds and seals the cells and the internal space. An internal blower is disposed in the casing. The internal blower circulates the air in the casing so as to pass through an inner surface of the casing and a periphery of the cell including the radiation bus bar, and the heat is radiated to an outside from the inner surface of the casing. |
