PROBLEM TO BE SOLVED: To provide an oxygen supplying machine which is reduced in the size and the weight and requires a little electricity to work by reducing the size of an air blowing device for supplying air to a gas separation membrane. SOLUTION: The oxygen supplying machine is equipped with the gas separation membrane 10 producing air of high oxygen concentration, the air blowing device 28 for making the air passing through the air separation membrane flow, a discharge nozzle 34 for supplying the produced air of the high oxygen concentration to a user, and a control unit 31 which controls to supply the air of the high oxygen concentration from the discharge nozzle 34 at the time of inspiration by the user and to stop supplying the air of the high oxygen concentration from the discharge nozzle 34 at the time of expiration. Consequently, the reduction in the size is achieved by reducing a load on the air blowing device 28 for supplying air, and the oxygen supplying machine which is reduced in size and weight and requires a little electricity to work is obtained.
