PROBLEM TO BE SOLVED: To provide an air supply device capable of performing air supply control according to atmospheric pressure with a simple structure. SOLUTION: In an air supply device supplying air to a device 200 which is supplied with air by operating movable members 1, 2 and delivering air, a motor 100 operating the movable members 1, 2, a consumed electric power detection device 40 detecting measured value relating to electric power consumption of the motor 100, a delivery air pressure detection means 26 detecting pressure of delivered air, and a control means 40 controlling rotation speed of the motor 100 are provided. The control means 40 calculates a reference value relating to electric power consumption required by the motor 100 at standard atmospheric pressure based on rotation speed of the motor 100 and air pressure detected by the delivery air pressure detection means 26, and controls rotation speed of the motor 100 based on the reference value and a measured value detected by an electric power consumption detection means 40.
