PURPOSE: An oxygen generator with oxygen concentration display part is provided which has simple structure and operating mechanism, generates oxygen having a constant concentration, is compactly installed in a case and visually recognizes current concentration of oxygen through display part. CONSTITUTION: The oxygen generator(10) with oxygen concentration display part comprises a main body(15a) comprising a case(11) comprising air inlet pipe(16) and oxygen outlet pipe(18), a pump which is installed in the case, and to which an external electricity is impressed to pump the air by receiving an external air through the air inlet pipe, an oxygen separator which is connected to the pump, through which the air exhausted from the pump passes, and which generates oxygen to be exhausted through the oxygen outlet pipe by separating oxygen in the air, and a humid oxygen generation preventing means for preventing discharge of moisture through the oxygen outlet pipe; an oxygen concentration sensor(78) for sensing oxygen concentration of indoor; and a display part(12a) connected to the oxygen concentration sensor to display oxygen concentration in such a manner that a value obtained by calculating a ratio of indoor oxygen concentration to inputted desired concentration in percentage is displayed.
