[Problem to be Solved] To improve blowing circulation efficiency inside the sealed type battery back, to thereby achieve a simplification of the structure, homogenization of the temperature distribution inside the battery pack, and a desired cooling effect.[Solution] A cooling structure for a battery pack (1) comprising a plurality of battery modules (31, 32) inside a battery case (10, 20), in which: the battery case is formed of a thermally conductive material as a heat dissipation member; the plurality of battery modules are fixedly arranged inside the battery case with a gap (310, 312, 320, 322, 330) between one another; the battery case comprises thereinside a blower fan (5) arranged on an upper side in a vehicle height direction with respect to the plurality of battery modules, and a blower duct (4; 41, 42) for pressure-feeding air sent out from the blower fan to at least one outlet (417, 418, 427, 428) positioned in the middle of the plurality of battery modules in a vehicle longitudinal direction and a vehicle width direction; and the cooling structure is configured such that the air (Fa, Fb, Fc, Fd) blown from the outlet passes through the gap in the plurality of battery modules and a gap between the plurality of battery modules and an inner face of the battery case, to be circulated to the blower fan.
