Abstract
A vehicular headlamp equipped with a light source bulb composed of a bulb body and a bulb supporting portion for supporting the bulb body and with a reflector in which a bulb insertion hole for insertion of the bulb body of the light source bulb is formed. An annular wall is formed around the bulb insertion hole of the reflector and a bulb abutment face on which the body supporting portion is made to abut from behind is formed in the annular wall. A notch portion that is notched forwards from the bulb abutment face is formed in the annular wall. Accordingly, the heat generated within the reflector is dissipated into the external space and the possibility of heat deformation of the reflector is reduced.
