PROBLEM TO BE SOLVED: To facilitate carrying work or the like by miniaturizing the whole air compressor, and suitably cool heat produced by a power supply control device while improving reliability and durability.SOLUTION: A pair of storage tanks 1 is connected to each other by a lower frame 5 and an upper frame 6, and extends parallel to each other in a longitudinal direction with the tanks laterally separated from each other. A compressor body 7 and an electric motor 12 are mounted on the upper frame 6 on an upper side between the tanks 1. The power supply control device 20 is arranged between the storage tanks 1 on the lower side of the electric motor 12 or the like, and the power supply to the electric motor 12 is inverter-controlled by the power supply control device 20. The power supply control device 20 includes a power supply part 23 provided to a metal casing 21 for a circuit and an inverter control part 30. A cooling air flow passage A is formed outside the casing 21 for the circuit. |
