Provided is a cooling structure such that even if this cooling structure is installed in a compact vehicle where the distance from the backseat to the rear end of the vehicle cabin is short, there is sufficient cooling efficiency of an electricity storage device while a living space is secured in the vehicle cabin. A battery is contained in an IPU (13) installed in the vehicle (1). The cooling structure for the battery comprises air intakes (14) opening into the vehicle cabin (2), and is provided with air intake ducts (15) and covers (16), the aforementioned intake ducts (15) extending from the air intakes (14) to the IPU (13), and the aforementioned covers (16) being disposed in such a way as to cover the air intakes (14) and having holes (16a) which are formed so as to cause the inside of the vehicle cabin (2) to communicate with the air intake ducts (15). The air intakes (14) are disposed in such a way that in those rear side sections of the vehicle cabin (2) which are in the vicinity of pillars C (8) located diagonally aft of the backseat (5), the openings of the air intakes (14) incline toward the inside of the vehicle cabin (2).
