PROBLEM TO BE SOLVED: To make it possible to safely manufacture gas-dissolved water having a high solution temperature and a high dissolved gas concentration and supply the same to a service space.SOLUTION: A gas-dissolved water manufacturing method includes a gas dissolution process in which dissolved gas comprising gas which is not self-decomposed in water is dissolved in supply water, and a heating process in which obtained gas is so heated as to become a target value Tof a solution temperature. According to the method, based on a measurement value T of a solution temperature of gas-dissolved water after heating in the heating process, a gas dissolution amount in the gas dissolution process is controlled so that a dissolved gas concentration of said gas-dissolved water does not exceed a saturation solubility in the measurement value T.SELECTED DRAWING: Figure 1 【課題】液温が高く、溶存ガス濃度の高いガス溶解水を安全に製造して使用場所に供給する。【解決手段】水中で自己分解しないガスからなる被溶解ガスを供給水に溶解させるガス溶解工程と、得られたガス溶解水を、液温の目標値Ｔ０となるように加熱する加熱工程とを含むガス溶解水の製造方法において、該加熱工程における加熱後の該ガス溶解水の液温の測定値Ｔに基づいて、該ガス溶解水の溶存ガス濃度が該測定値Ｔにおける飽和溶解度を超えないように該ガス溶解工程におけるガス溶解量を制御するガス溶解水の製造方法。【選択図】図１
