To provide a device for production of an isotonic ozone water downsized for general households and capable of simply producing the isotonic ozone water keeping high ozone concentration over a long time.
The device M for production of the isotonic ozone water comprises: a solution transfer part 1 for continuously, quantitatively transferring a solution comprising 0.9%-saline solution dissolving a salt in water; an ozone gas-generating part 2 for generating an ozone gas in an ozone generator 24 by supplying a velocity-controlled oxygen gas from a portable oxygen cylinder 21; a gas-liquid mixing part 3 for generating a gas-liquid mixing water by mixing the solution quantitatively transferred from the solution transfer part 1 with the ozone gas generated at the ozone gas-generating part 2 using a static mixer 31; a gas-liquid separation part 4 for separating the gas-liquid mixing water generated at the gas-liquid mixing part 3 into a waste gas insoluble in the solution and the isotonic ozone water dissolving ozone in the solution; a waste gas treatment part 5 for decomposing residual ozone included in the waste gas separated at the gas-liquid separation part 4 using a catalyst; and an isotonic ozone water-discharging part 6 for discharging outside the device, the isotonic ozone water separated at the gas-liquid separation part 4.
