(54) Vehicle headlamp device


(57) A subreflector (4L, 4R) of a vehicle headlamp (1L, 1R) acts as a vertical-wall structure and includes a first sub-reflecting surface (410) that reflects light (L1) from a light source (2L, 2R), and projects a first sub-light-distribution pattern on one side of a main light-distribution pattern (P). The subreflector (4L, 4R) also includes a second sub-reflecting surface (420) that reflects light (L2) from the light source (2L, 2R), and projects a second sub-light-distribution pattern between the main light-distribution pattern (P) and the first sub-light-distribution pattern. One side of the second sub-light-distribution pattern overlaps with the main light-distribution pattern (P), and the other overlaps with the first sub-light-distribution pattern.
