An automotive headlamp apparatus includes headlamp units (20R, 20L) placed in a vehicle (10) and a control unit (22) which controls the illumination of the headlamp units (20R, 20L). The headlamp units (20R, 20L) form a low beam distribution pattern (LBP) and an upper beam distribution pattern (HBP), and is configured so that a partial region (SA1) of the upper beam distribution pattern (HBP) can be non-illuminated. When the entirety of vehicle existent area of a vehicle-in-front travelling in front of a driver's vehicle is contained within the partial region, the control unit (22) controls the headlamp units (20R, 20L) in such a manner that the partial region (SA1) is non-illuminated; when at least a part of the vehicle existent area is contained within a region (SA2) of the upper beam distribution pattern (HBP) which is other than the partial region (SA1), the control unit (22) controls the headlamp units (20R, 20L) in such a manner that the upper beam distribution pattern (HBP) is not formed. The control unit (22) is adapted to determine the vehicle presence area, based on a correction range which is wider by predetermined horizontal angle than a basic range where the vehicles-in-front exist, wherein the basic range is defined by a horizontal angle range extending between a position of a leftmost vehicle-in-front and a position of a rightmost vehicle-in-front.
