A headlight unit (100) includes a light source (101), a light guide member (102), a projection lens (103), and a drive unit (112). The light source (101) emits a light beam for irradiating a forward area in a traveling direction. The light guide member (102) receives the light beam and emits planar light having a divergence angle. The projection lens (103) receives the planar light and projects it forward. The drive unit (112) changes a positional relationship between the light guide member (102) and the projection lens (103). The drive unit (112) is disposed in a region overlapping with the projection lens (103) in a direction perpendicular to an optical axis of the light guide member (102) from the light guide member (102), as optically viewed from an optical axis direction of the projection lens (103).
