In a battery pack structure for electric vehicles that a plurality of battery modules (21), (22), (23), and an LB controller 6 are mounted in an interval space of a battery pack case (1), clearances, ensured when the plurality of battery modules (21), (22), (23) are mounted in the internal space of the battery pack case 1, are configured as temperature-adjustment air passages through which temperature-adjusting air flows. The plurality of battery modules (21), (22), (23) and the LB controller (6) are arranged at positions along one common intersecting passage (37) of the temperature-adjustment air passages, the intersecting passage facing the plurality of battery modules. Furthermore, a heavy-electric harness (97), via which the plurality of battery modules (21), (22), (23) and the LB controller (6) are connected to each other, is wired along the intersecting passage (37). Therefore, when connecting the plurality of battery modules and the LB controller to each other via the harness, it is possible to ensure smooth flow of temperature-adjusting air, while improving both the harness-wiring workability and the harness durability.
