In a vehicle battery unit, since a second support plate (30B) and a second end plate (29B) of a second battery module (22B) having a plurality of battery cells (21) stacked are placed on top of a first support plate (30A) and a first end plate (29A) of a first battery module (22A) having a plurality of the battery cells (21), it is possible to prevent the weight of the second battery module (22B) from being imposed on the battery cells (21) of the first battery module (22A). Moreover, since it is not necessary to provide on the exterior of the first battery module (22A) a member for supporting the weight of the second battery module (22B), it is possible to reduce the dimensions of the first battery module (22A).
