[PROBLEMS] To provide an apparatus for producing an ozone water which can dissolve an ozone gas into a raw water at a high concentration and also can produce it at a low cost. [MEANS FOR SOLVING PROBLEMS] An apparatus for producing an ozone water which comprises an aspirator (120) for contacting a raw water with an ozone gas formed in a section (110) for generating an ozone gas, and a gas-liquid dissolution section being connected to the aspirator (120) and comprising a tube (130) having concave portions (131) and convex portions (132) formed alternately on the inside surface thereof, and which dissolves an ozone gas into the raw water at a high concentration, through allowing a mixed fluid of an ozone gas and the raw water to flow in the tube (130). |
