PROBLEM TO BE SOLVED: To enhance accuracy of optical axis control in auto-leveling control using a low cost distance sensor. ! SOLUTION: An optical axis control device for a headlamp 13 provided in a vehicle having a first portion in which inclination with respect to a road surface fluctuates and a second portion in which the inclination with respect to the road surface hardly fluctuates includes: a distance detection unit 11 mounted in a predetermined position of the first portion of the vehicle and for detecting a distance with a predetermined position of the second portion of the vehicle; a vehicle body inclination angle determination unit 21 for acquiring an inclination angle with respect to a road surface in a front and back direction in the first portion of the vehicle by using the distance detected by the distance detection unit 11; an optical axis control amount setting unit 22 for acquiring an optical axis control amount of the headlamp based on the inclination angle acquired from the vehicle bod |
