摘要：
A vehicle headlamp is provided with an upper stage light source unit, a middle stage light source unit, and a lower stage light source unit. The upper stage light source unit, the middle stage light source unit, and the lower stage light source unit are provided at a lamp body constituting a lamp member by way of a support member. A low beam light distribution pattern is formed on a front side of a vehicle by overlapping light from the respective light source units. The lower stage light source unit includes two subunits, the two subunits commonly share a single cylindrical lens.
