PROBLEM TO BE SOLVED: To provide a technology for improving heat dissipation properties of a lighting fixture unit.SOLUTION: A lighting fixture unit 10 is a lighting fixture unit used in a vehicular lighting fixture, and includes: a light emitting element; a projection lens 28 projecting at least a part of light emitted from the light emitting element to the front of the lighting fixture as a light source image; and a heat dissipation member arranged around a space including an optical path between the light emitting element and the projection lens and dissipating heat emitted from the light emitting element to the exterior of the lighting fixture unit. The heat dissipation member has a penetration part formed so as to communicate between the exterior of the lighting fixture unit and the space, and a heat dissipation fin provided across the opening of the penetration part. |
