Abstract: A cooling device includes: an evaporator configured to cool a battery pack by evaporating a heat medium by heat exchange between the battery pack and the heat medium, the battery pack including a plurality of battery cells arranged in an arrangement direction; a condenser disposed above the evaporator and configured to radiate heat of the heat medium to an external fluid by condensing the heat medium by heat exchange between the heat medium and the external fluid; a gas-phase passage configured to guide the heat medium in a gas phase from the evaporator to the condenser; and a liquid-phase passage configured to guide the heat medium in a liquid phase from the condenser to the evaporator, wherein a cooling amount at an end of the evaporator in the arrangement direction is lower than a cooling amount at a center of the evaporator in the arrangement direction.
