A negative pressure sensor abnormality detection apparatus includes a negative pressure sensor that outputs a signal corresponding to a negative pressure that a negative pressure pump generates, the negative pressure assisting a vehicle driver's brake operation; a negative pressure detection part that detects the negative pressure based on the signal that is output by the negative pressure sensor; a number-of-rotations counting part that counts the number of rotations of the negative pressure pump; and an abnormality determination part that determines that the negative pressure sensor is in an abnormal condition if, under a condition where a change in the driver's brake operation falls within a predetermined range, a change in the negative pressure detected by the negative pressure detection part along with an increase in the number of rotations counted by the number-of-rotations counting part is out of a predetermined range.
