PROBLEM TO BE SOLVED: To provide a cooling apparatus for cooling the inside of a greenhouse for cultivating plants by spraying micro mist, when it is superheated. SOLUTION: An intake blower with a nozzle is installed at least one side out of the lower part and the middle high part of the greenhouse. The outlet side of the intake blower locating inside of the greenhouse is brought to be lateral when it is installed to the lower part, while it is brought to be inclined downward when it is installed to the middle high part. The nozzle is attached to the outlet side and spraying is carried out into the greenhouse from the nozzle, and at the same time, the spraying is put on an air blow discharged from the intake blower, while an exhaust blower for exhausting air in the greenhouse to the outside is installed to the upper part of the greenhouse, and the relative positional relation of the intake blower with the nozzle to be installed to the inside of the greenhouse and the exhaust blower to be installed to the upper part of the greenhouse is set so that the spraying from the nozzle can circulate inside of the greenhouse.
