[Problem] A driver state determination apparatus capable of detecting the decline of the physical function of a driver and confirming the determination of an abnormal state early on in a stage that is sufficiently before the driver becomes unable to drive is provided.[Means for solution] A driver state determination apparatus 10 includes: a vibration apparatus 14 that gives vibration to a steering wheel 2; a vibration detector 16 that detects the vibration of the steering wheel; and a controller 18 that controls the vibration apparatus. The controller gives vibration at a predetermined excitation frequency f0 to the steering wheel by the vibration apparatus, calculates a steering torque level at the excitation frequency based on the vibration detected by the vibration detector, and determines that a driver is in an abnormal state when an average value A of the steering torque level while the vibration is being given is equal to or more than a first threshold value Th1 and/or a standard deviation SD of the steering torque level while the vibration is being given is equal to or more than a second threshold value Th2.
