A control unit of an optical axis control device for a headlight calculates a first vehicle angle (θα) and a second vehicle angle (θβ) at different timings in traveling of a vehicle, and calculates a third vehicle angle (θs) at which a difference between acceleration signals in a front-rear direction (ΔX) is zero. The control unit calculates a representative value (θS) based on a distribution of a plurality of third vehicle angles (θs), and generates a signal for operating an optical axis of the headlight based on the representative value (θS).
