A headlight optical axis control apparatus calculates an inclination angle of a vehicle with respect to a road surface from a ratio of a difference between acceleration signals in the front-and-rear direction measured at two time points (kn, kn+1) to a difference between acceleration signals in the up-and-down direction measured at the two time points (kn, kn+1), the two time points being in the vicinity of a time when the attitude of a vehicle body becomes equivalent to a stationary state, in a period from a time when the travelling vehicle stops to a time when the vehicle body comes to a halt.
