Light guide, light source apparatus, and electronic apparatus

A light guide is disclosed. The light guide includes an incident surface, an exit surface, and a light guide section. Light emitted from a plurality of light emitting devices disposed in line enters from the incident surface. The exit surface is formed in a shape causing light to be concentrated. The light which has entered from the incident surface exits from the exit surface. The light guide section is bent. The volume of the light guide gradually increases in a direction from the incident surface to the exit surface.
