Abstract
A headlight module includes a first light source that emits first light, and a first optical unit. The first optical unit includes a first optical surface that reflects the first light, and a lens surface that projects illuminating light including the first light reflected by the first optical surface. An edge part of the first optical surface close to the lens surface includes a first edge part and a second edge part differing from each other in a position in a direction orthogonal to an optical axis of the lens surface, and a position of the second edge part in a direction of the optical axis is closer to the lens surface than a position of the first edge part in the direction of the optical axis.
