In a cooling structure for a battery pack, a case bottom wall of a first battery case is divided into left and right case bottom walls. A first cooling medium jacket includes left and right first cooling medium jackets formed respectively in the left and right case bottom walls. Left ends of the left first cooling medium jacket and second cooling medium jacket are made to communicate with each other via a left cooling medium passage. Right ends of the right first cooling medium jacket and second cooling medium jacket are made to communicate with each other via a right cooling medium passage. Accordingly, it is possible to simplify the structure of a cooling medium passage for supplying cooling medium to a cooling medium jacket of battery cases on two levels.
