PROBLEM TO BE SOLVED: To provide a gas dissolving module which can stably discharge a condensate collected in a gas chamber over a long period, is free from troubles accompanying the discharge of the condensate, and can produce gas-dissolved water with a desired concentration. SOLUTION: The gas dissolving module is divided into a water chamber and the gas chamber by a gas-permeable membrane. Water to be treated is fed to the water chamber, and gas to be dissolved in the water to be treated is fed to the gas chamber. One end of a condensate discharge pipe is made to communicate with the gas chamber, and the other end is connected to a pressure reducing device without a mechanical driving part, for example, an aspirator, to discharge the condensate collected in the gas chamber.
