PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing cool water capable of efficiently cooling hot water generated by the cooling of external equipment and supplying as cool water again to the external equipment. SOLUTION: This cool water manufacturing device 10 comprises a cooling tower 11 cooling high temperature water generated by the external equipment and returning to the external equipment, a pressure reducing means 12 holding the inside of the cooling tower 11 in a reduced pressure state, water receiving parts 13 installed in multiple stages in the cooling tower 11 and, while making the supplied water, stagnant downwardly moving the supplied water in order, and water absorbing materials 14 installed on the water receiving parts 13 and having gas permeability. The water supplied to the cooling tower 11 in a reduced pressure state is, while being stagnant temporarily in the water receiving parts 13, moved in order to the water receiving parts 13 located under the cooling water and then moved to the bottom of the cooling tower 11. A part of the water made stagnant in the water receiving parts 13 is diffused in the water absorbing members 14 and evaporated from the surfaces thereof to remove latent heat and lower the temperature of the remaining water.
