Abstract: A surface light source apparatus includes an end face for taking in light emitted from a light source and a main surface for emitting the light. The surface light source apparatus further includes a plurality of structure bodies formed on an opposed surface disposed opposite to the main surface in the surface light source apparatus, each of which has a reflecting surface facing the point light source. Each structure body has a cut-off portion which removes a portion on the reflecting surface in a longitudinal direction of the structure body and in a height direction.
