An oxygen generator is provided to discharge condensed water obtained from high-humidity oxygen generated from an oxygen generator effectively, thereby improving the dehumidifying efficiency, by using a dehumidifying unit. An oxygen separator(110) has a membrane(111) for separating nitrogen and oxygen from inputted air. A dehumidifying unit(200) separates moisture from high-humidity oxygen, which is inputted from the oxygen separator, to exhaust low-humidity oxygen to the outside. The dehumidifying unit has a condensed water storage bath for storing condensed water separated from the high-humidity oxygen. A flow change valve(120) is installed between the oxygen separator and the dehumidifying device. The flow change valve includes a first port(121) connected to an oxygen exhaust line at an oxygen exhaust port side of the oxygen separator, a second port(122) connected to an oxygen supply line at an oxygen supply port side of the dehumidifying unit, and a third port(123) connected to a nitrogen exhaust line communicating with a nitrogen exhaust port of the oxygen separator. A controller controls the opening and closing of the flow change valve so that two of the first port, the second port, and the third port are selectively connected. Further, the dehumidifying unit contains a discharge valve connecting selectively an exit of the condensed water storage bath and a flow passage of the oxygen supply port.
