The case, in particular, includes a bottomed trough and a lid, the trough having a space as a cell storage portion defined between inner and outer wall portions paired to form a loop and a space as a hollow surrounded by the inner wall portion and penetrating the trough from top to bottom, the lid closing a top opening of the cell storage portion. The battery cells are arranged in a loop along the inner and outer wall portions, whereby a rise and variation in their temperature can be restrained.
