To stabilize a supply air dew point temperature on the secondary side even when a regenerated air amount is changed without complicated control.
The dehumidifier includes a controller 32 for calculating the amount of air to be supplied to the secondary side based on differential pressure of a differential pressure gauge 28 and controlling the rotational speed of a suction rotor 12 rotated by a motor 20, and a temperature/humidity sensor 26 for detecting absolute humidity of treated air at a position before passing a treating area 36 of the suction rotor 12. The controller 32 calculates the regenerated air amount based on the absolute humidity of the treated air detected by the temperature and humidity sensor 26, the supply air amount calculated by the controller 32, and a set value of the supply air dew point temperature set in advance, and controls the regenerated air amount based on the calculated result.
