A vehicle headlamp has a focused-beam lamp unit, and a diffused-beam lamp unit. The focused-beam lamp unit has a first semiconductor light emitting device having a first rectangular light emitting surface, and a first optical member that projects light from the first semiconductor light emitting device to form a focused beam pattern. The diffused-beam lamp unit has a second semiconductor light emitting device having a second rectangular light emitting surface, and a second optical member that projects light from the second semiconductor light emitting device to form a diffused beam pattern, the diffused beam pattern being wider than the focused beam pattern in a direction along a vertical line in front a vehicle on which the vehicle headlamp is mounted. The focused-beam lamp unit and the diffused-beam lamp unit are arranged to form a light distribution pattern by combining the focused beam pattern and the diffused beam pattern.
