Abstract
A headlight unit includes: a light source that emits a light beam for irradiating a forward area in a traveling direction; a light guide portion that receives the light beam and forms planar light having a divergence angle; a projection lens portion that projects the planar light forward; and a drive unit that changes a position of the projection lens portion. The drive unit is disposed in a region overlapping with the projection lens portion, as optically viewed from an optical axis direction of the light guide portion or the projection lens portion.
