The invention relates to a control device for an electrically-driven vacuum pump. The control device stops operation of an electrically-driven vacuum pump for generating negative pressure in a negative pressure chamber of a brake booster when the vacuum pump is operated and a gradient of increasing of a booster negative pressure representing a magnitude of a difference between pressure in the negative pressure chamber and the atmospheric pressure is smaller than or equal to a predetermined stop gradient threshold.
