Zusammenfassung:	Provided is a technique of shaping light emitted from a linear light source while preventing mechanism upsizing. A light shaping apparatus includes a linear light source having a light-emitting point, a reflective mirror portion having an orthogonal parabolic surface, and an optical device disposed at a convergence point. Light emitted from the linear light source is reflected by the reflective mirror portion surrounding the linear light source, and further converges at the convergence point. The reflective mirror portion has a rotation axis extending along the longer-side direction of the linear light source. The light-emitting point of the linear light source is located on the rotation axis of the reflective mirror portion. The optical device has an entrance end face located at the convergence point. The entrance end face is an end face on which the light from the linear light source is incident.
