A control device for an electric vacuum pump that generates a negative pressure includes a negative-pressure detector for detecting the negative pressure generated by the electric vacuum pump and a pump stop control unit that is adapted to stop the electric vacuum pump when the negative pressure detected by the negative-pressure detector is not less than a predetermined value. The pump stop control unit is configured to determine an OFF timing at a present stage of the electric vacuum pump based on reference pump-filling-performance data, which is data about a reference negative pressure ratio relative to an elapsed time at an initial stage of the electric vacuum pump, and by referring to present pump-filling-performance data, which is data about a present negative pressure ratio relative to an elapsed time at the present stage of the electric vacuum pump.
