In a headlamp light distribution control device, a light source configured by a pair of lamps mounted in a forward vehicle is extracted from an image of the forward vehicle if a distance to the forward vehicle is less than a predetermined value, and the number of the extracted light sources is judged. When the number of the extracted light sources is two, an irradiation direction of a headlamp is controlled such that a shielded area is set in an irradiation area to prevent an area including the lamp of the forward vehicle from being irradiated. When the number of the extracted light sources is one, the irradiation direction is controlled such that a shielded area is set in the irradiation area to have a margin in right and left directions larger than the shielded area set when the number of the extracted light sources is two.
