PROBLEM TO BE SOLVED: To provide a gas dissolving device where a gas is dissolved in a liquid in a supersaturation state and the supersaturation state can be stably maintained and further which can be easily attached to a water server and the like.SOLUTION: A gas dissolving device 1 generating hydrogen water by dissolving hydrogen in water and discharging from a taking out port includes: a dissolution tank 4 where generated hydrogen water is introduced, pressurized and stored; and a pressure reduction transfer means 5 where pressure fluctuation in a tubular path caused by the discharge action of the hydrogen water from the taking out port in the tubular path connecting the dissolution tank to the taking out port 10 is prevented and a laminar flow is formed.SELECTED DRAWING: Figure 1 |
