To provide a lighting fixture unit for a vehicle headlight capable of eliminating light distribution unevenness in which a nearer side of an illuminated region becomes especially darker than other illuminated regions.

A lighting fixture unit for a vehicle headlight comprises: a first light-shielding shade 18 arranged between a reflector 17 (20) and a projection lens 15, and for shielding a part of light reflected from the reflector 17 (20) and forming a predetermined light distribution pattern; and a second light-shielding shade 19 arranged in the upper side of the first light-shielding shade 18, and for shielding a part of the light reflected from the reflector 17 (21) and making luminous intensity in the lower region in the predetermined light distribution pattern lower than that of other regions in the predetermined light distribution pattern. With this configuration, regarding light-shielding properties in the light reflected from the reflector 17 (20, 21), the second light-shielding shade 19 is set such that the luminous intensity in the lower region in the predetermined light distribution pattern becomes higher from the lower to upper sides, and brightness becomes gradually higher from nearer to farther sides of the illumination region.
