PROBLEM TO BE SOLVED: To provide a vacuum cooling method, and its device preventing scattering, and boiling over of an object to be cooled due to bumping in a cooling tank, and capable of improving cooling capacity. SOLUTION: The device is provided with the cooling tank 3, a first vessel 5 arranged in the cooling tank 3 and holding the object 4 to be cooled, a second vessel 7 storing a liquid 6 and arranged such that an outer circumferential face of the first vessel 5 and the liquid 6 are in a contact state, and a pressure reduction means 8 for reducing a pressure in the cooling tank 3. Or it is provided with the cooling tank 3, the first vessel 5 arranged in the cooling tank 3 and holding the object 4 to be cooled, an impregnation member provided in a contact state with the outer circumferential face of the first vessel 5 and impregnated with the liquid 6, and the pressure reduction means 8 for reducing the pressure in the cooling tank 3.
