A pattern-variable headlamp includes a light source, a reflector, a movable shade that switches a position between a first position, a second position, and a third position to form a first light distribution pattern, a second light distribution pattern, and a third light distribution pattern, respectively, from the light reflected from the reflector, a projection lens that irradiates the light distribution pattern to a road surface, a first solenoid that moves the movable shade to switch from the first position to the second position, a second solenoid that moves the movable shade to switch from the first position to the third position, and an elastic returning unit that returns the movable shade to switch from the second position to either of the first position and the third position, or from the third position to the first position.
