PROBLEM TO BE SOLVED: To provide an ozone reactor in which the treatment ability is improved by facilitating mixing of ozone and raw water to increase the quantity of contact of both. SOLUTION: The ozone reactor, in which ozone water prepared by dissolving ozone gas into water, or mixture of the ozone water and ozone gas is brought into contact with raw water and, thereby, ozonation of raw water is performed, comprises an injection device 15, 15a which ejects the ozone water 13 or the mixture of ozone gas 9, 9a and the ozone water as an ozone jet 14, 14a having an ejection speed larger than a flow speed of the raw water in a direction different from the flow direction of the raw water 4, wherein ejection holes of the injection devices 15, 15a are arranged on such positions that the ejection holes adjacent to each other in the flow direction are not superimposed as viewed from the flow direction of the raw water 4.
