An optical axis controller includes an adjuster(6) which adjusts the optic angle of an automotive headlamp (5), and a drive torque calculator (2b) which calculates the drive torque (T d ) applied to drive wheels of a vehicle (10). The optical axis controller also includes a determiner (3) which determines whether the vehicle (10) is in a static running state or in a dynamic running state, on the basis of the drive torque (T d ). The optical axis controller further includes a controller (4) which permits an adjuster (6) to adjust the optic angle if the determiner (3) determines that the vehicle (10) is in the static running state, and does not permit the adjuster (6) to adjust the optic angle if the determiner (3) determines that the vehicle (10) is in the dynamic running state. This configuration results in accurate determination of the running states suitable for correcting the optical axis.
