To provide a vehicle headlamp capable of reducing the number of lamp units to be mounted for reduced footprint of them by enabling switching between condensed light and diffused light of an identical lamp unit.

The lamp unit is provided with a light-emitting element 1 arranged facing a direction nearly orthogonal to the optical axis, a fixed reflecting mirror 2 to reflect the emitted light from the light-emitting element 1 to the front in the optical axis direction, a movable reflecting mirror 3 capable of moving between a position to cut off the light path and a position not to cut off the light path to the fixed reflecting mirror 2, and a gear 4 for moving the movable reflecting mirror 3.
