Beschreibung
Zusammenfassung:	A surface light source device includes a laser beam source, a laser beam guide rod for converting a laser beam into first linear light, an LED light source, an LED light guide rod for converting LED light into second linear light extended in the same direction as the first linear light, a reflecting bar for reflecting the first linear light and the second linear light, and a light reflecting portion formed in a box shape and having an opening portion with an emission side opened and a reflecting surface on an inside of the box shape. The first linear light and the second linear light are reflected by the reflecting bar and the reflecting surface, and are emitted from the opening portion.
