To provide a device for controlling an opening/closing device of a vehicle door which can slightly suppress idle running of the door due to the use of a mechanical clutch so as to reduce the impact on a motor and the clutch.

In opening/closing control, holding of a door by a fully-opening holding latch device is switched to the release side based on a closing command, and when the door operation speed obtained after the release reaches a determination speed va or more, drive of a PSD motor is started and automatic closing operation of the door is performed.
