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.

[ What is claimed is:] [1.]1. A vehicular headlamp assembly, comprising:a light source bulb comprising a bulb body, a bulb supporting portion for supporting said bulb body; anda reflector,said reflector having an ellipsoid shape terminating at an open forward end and a smaller open rear end,a bulb insertion hole for insertion of said bulb body of said light source bulb being formed in said smaller open rear end of said reflector,said reflector comprising an annular wall on an exterior thereof disposed around said bulb insertion hole and axially extending along a optical axis of said reflector,said annular wall comprising a bulb abutment face on an exterior surface thereof, said exterior surface being substantially perpendicular to said optical axis of said reflector,said bulb supporting portion of said light source bulb abutting said bulb abutment face from a direction of bulb insertion, andsaid annular wall having at least one notch portion that extends though said annular wall, said notch portion comprising an area indented from said bulb abutment face and extending forward from said bulb abutment face to said bulb insertion hole on the exterior surface of said reflector, wherein said notch portion facilitates heat dissipation by allowing heat to escape from inside said reflector.
