PROBLEM TO BE SOLVED: To provide a production apparatus of a gas dissolved water possible to be continuously and stably operated over the long term, and to provide its production method. SOLUTION: A raw water is supplied into a liquid phase room 11b of a gas-dissolving membrane module 11 and a gas is supplied into a gas phase room 11c. The gas permeates a gas permeation membrane 11a and is dissolved in the raw water in the liquid phase room 11b to give the gas dissolved water, which is supplied to a use point through a gas-dissolved water pipe 23. When an amount of a condensed water measured by a condensed-water detection means 13 exceeds a determined value, a first valve 24a is closed, a second valve 24b is opened and a gas suction pump 14 is activated. Therefore, the condensed water stored between the valve 24a and 24b is vaporized by a membrane module 12 for vaporizing of a condensed water to form water vapor, which is discharged through the suction pump 14.
