ABSTRACT:
A lamp unit of a vehicle lamp includes a projection lens arranged on an optical axis extending in the longitudinal direction of a vehicle, a light-emitting element arranged so as to face upward behind a rear focal point of the projection lens and in the vicinity of the optical axis, and a reflector arranged so as to cover the light-emitting element from above and to reflect the light from the light-emitting element forward toward the optical axis. The light-emitting element has a plurality of light-emitting chips arranged so as to be adjacent to each other in a vehicle width direction. A mirror member is provided between the reflector and the projection lens. The mirror member includes an upward reflecting surface that upward reflects a portion of the reflected light from the reflector. A diffusing and reflecting portion that diffuses and reflects the reflected light from the reflector is formed in the upward reflecting surface so as to bridge over the optical axis in the vehicle width direction.
