The case side wall and the upper cover 24 are sealingly connected at the upper wall. The case side wall and the lower cover are sealingly connected by an inner flange. A first member of one steel plate of the case side wall forms a portion of the upper wall that is sealingly coupled to the upper cover, an inner flange, and an inner wall in one piece seamlessly and without holes. The inner wall serves as a waterproof wall, and even if water enters the tubular portion of the case side wall, it is possible to prevent water from entering into the battery accommodating space of the battery case.
