An automotive headlamp apparatus includes a left lamp unit, a right lamp unit and a headlamp apparatus control unit. Each of the left lamp unit and the right lamp unit includes a bulb, a movable shade, a shade moving mechanism and a fixed shade. Each movable shade can advance or recede with respect to the light axis of the bulb, and forms an individual light distribution pattern for a low-beam by shielding part of a light at an advanced position while allowing formation of a partial shape of a light distribution pattern for a high-beam at a receded position. The fixed shade forms the partial shape of the light distribution pattern for a high-beam when the movable shade is located at the receded position. A pattern control unit determines each shape of the individual light distribution patterns by controlling each of the shade moving mechanisms in the left lamp unit and the right lamp unit, and also determines a shape of a synthesized light distribution pattern by superimposing each of the individual light distribution patterns one on another.
