PROBLEM TO BE SOLVED: To provide an apparatus for producing ozonized water which is adaptive to a wide range of changes of an ozonized water supply flow rate by enabling a mixing pump to be operated in a range for high efficiency even under operating condition with a large change in the ozonized water supply flow rate. SOLUTION: The apparatus for producing the ozonized water includes: an ozonized water tank 1 to store the ozonized water; a raw water line 2 for supplying raw water to the ozonized water tank; an ozonized water line 3 for taking out the ozonized water from the ozonized water tank; a plurality of mixing lines 4a, 4b and 4c which form flow passages for taking out the water from the ozonized water tank, mixing an ozone gas and making the water flow into the ozonized water tank again; mixing pumps 5a, 5b and 5c installed in mixing lines respectively; and an ozone gas generating apparatus for supplying the ozone gas at the suction sides of the mixing pumps. The apparatus for producing the ozonized water has a construction to increase and decrease the number of mixing pumps to be operated so as to supply the ozone gas only to mixing lines in which the mixing pumps to be operated are installed.
