In a headlamp of an automobile, a reflector is divided to an upper reflector member (1) positioned above an optical axis (Z-Z) and a lower reflector member (3) including the optical axis (Z-Z); the upper reflector (1) is rotatable and provided with a reflection face (10) for forming a diffusing luminous intensity distribution pattern (WP); the lower reflector member (3) is provided with a light source bulb (4), and is rotatable and provided with a reflection face (30) for forming a reference luminous intensity distribution pattern (LP). Therefore, the diffusing luminous intensity distribution pattern and the reference luminous intensity distribution pattern can independently or simultaneously be changed by rotating the upper reflector member (1) and the lower reflector member (3) independently or simultaneously. Accordingly, visibility is improved when an automobile is running on a curved road. <IMAGE>
