There is provided a vehicle battery unit including: a battery module including a battery cell stack where chargeable-dischargeable battery cells are stacked; a housing case including upper and lower cases and having a housing space to house the battery module; a flow-path forming plate defining a plate-shaped refrigerant-flow-path with the lower-case bottom at a predetermined flow-path interval, the battery module being cooled with a liquid-refrigerant flowing through the plate-shaped refrigerant-flow-path from a bottom-rear-surface of the lower case, the plate-shaped refrigerant-flow-path having a flow region accounting for 90% or more of the bottom-rear-surface of the lower case; a refrigerant-supply-nozzle being a slit or flat nozzle, the liquid-refrigerant being supplied through the refrigerant-supply-nozzle to flow over 90% or more of a flow path width of the plate-shaped refrigerant-flow-path; a liquid-refrigerant-supply header that supplies the liquid-refrigerant to the refrigerant-supply-nozzle; and a liquid-refrigerant-discharge header that discharges the liquid-refrigerant from the plate-shaped refrigerant-flow-path.
