Abstract
A vehicle headlamp () includes: a lamp unit (); a boundary determination unit (); and a control unit (CO), in which the control unit (CO) controls the lamp unit () such that an illuminance of light irradiating respective irradiation spots () in an irradiation spot row () formed of irradiation spots () irradiated with light from the light emitting elements () overlapping the boundary () is equal to or lower than the illuminance of light irradiating adjacent irradiation spots () in the bright region side of the irradiation spots (), and is equal to or higher than the illuminance of light irradiating adjacent irradiation spots () in the dark region side of the irradiation spots (), and so that the total amount of light irradiating the irradiation spot row () decreases depending on the proportion of a portion of the irradiation spot row () that overlaps the dark region.
