To provide a vehicle battery pack which can meet specification requests of a battery in a limited installation possible area while increasing a battery capacity which can be mounted on an electric vehicle.SOLUTION: A vehicle battery pack includes: a first battery housing part disposed in a first space between side rails; a first battery; a second battery housing part which has a width larger than a width of the first battery housing part as viewed in a vehicle width direction at a second space located below the first space in a vehicle height direction; and a second battery. The first battery and the second battery include rectangular parallelepiped battery modules, each of which houses multiple battery elements aligned in one direction and has an outer shape extending in the one direction. The one direction in the battery module forming the first battery is a vehicle longitudinal direction, and the one direction of the battery module forming the second battery is a vehicle width longitudinal direction.SELECTED DRAWING: Figure 6
