A battery and an electrical apparatus accommodated in a battery pack body (1, 4) are effectively cooled. The battery pack body (1, 4) includes a battery region in which a battery module (2) is accommodated and an electrical apparatus region in which the electrical apparatus is accommodated. An air-suction portion (3) and an air-exhaust portion (37) are formed in the battery pack body (1, 4). Air which flows through the air-suction portion (36) is made to flow in the battery pack body (1, 4), thereby cooling the battery module (2) and the electrical apparatus and then, the air is made to flow out through the air-exhaust portion (37). The electrical apparatus region includes an electrical apparatus cover (27) which covers at least a portion of the electrical apparatus and which branches air which is sucked through the air-suction portion.
