An object is to provide a technique capable of accurately determining an awakening degree. An awakening degree determination apparatus includes a change amount acquisition unit, a frequency calculation unit, and an awakening degree determination unit. The change amount acquisition unit acquires an angle change amount, an inclination change amount, and a position change amount. The frequency calculation unit calculates an angle frequency, an inclination frequency, and a position frequency. When at least one of the angle frequency, the inclination frequency, and the position frequency exceeds a fourth threshold value, a fifth threshold value, and a sixth threshold value, the awakening degree determination unit determines that an awakening degree of a driver of the vehicle decreases.
