Abstract: A light projection unit capable of improving light use efficiency is provided. This light projection unit includes: a fluorescent member that includes an illuminated surface to which laser light is directed, converts at least part of the laser light into fluorescent light and outputs the fluorescent light from chiefly the illuminated surface; and a reflection member that includes a first reflection surface which reflects the fluorescent light output from the fluorescent member. The illuminated surface of the fluorescent member is inclined with respect to a predetermined direction in such a way that the illuminated surface faces in a direction opposite to a light projection direction.
