A first battery module (22A) obtained by stacking a plurality of battery cells (21) has a first supporting plate (30A) and a first end plate (29A). A second battery module (22B) obtained by stacking a plurality of battery cells (21) layered has a second supporting plate (30B) and a second end plate (29B). The second supporting plate (30B) and the second end plate (29B) are mounted on the first supporting plate (30A) and the first end plate (29A), thereby preventing the weight of the second battery module (22B) from being applied to the battery cells (21) of the first battery module (22A). In addition, since it is not necessary to provide a member supporting the weight of the second battery module (22B) to the outside the first battery module (22A), the first battery module (22A) can be reduced in size.
