1. A headlight module comprising:
a first light source for emitting first light; and
an optical element including a first incident surface for receiving the first light, a first reflecting surface for reflecting the received first light, and a first emitting surface for emitting the light reflected by the first reflecting surface,
wherein the first incident surface changes a divergence angle of the first light to form a light distribution pattern,
wherein the headlight module further comprises a second light source for emitting second light,
wherein the optical element further includes a second incident surface located on a back surface side of the first reflecting surface,
wherein the second light emitted from the second light source enters the optical element through the second incident surface,
wherein the first emitting surface has positive refractive power, and
wherein in a direction of an optical axis of the first emitting surface, an edge portion of the first reflecting surface on a first emitting surface side includes a point located at a focal position of the first emitting surface.
