Abstract: Provided a light guide (11) including side surfaces on which light is incident, a reflection prism surface having plural prisms (12) on which light is reflected, and a light emitting surface from which the light is emitted, in which the reflection prism surface includes a first region (PA) in which a pitch of the prisms (12) varies and a second region (TA) in which a depth of the prisms (12) varies. In the light guide (11), the first region is arranged in the side surface on which the light is incident, and a second region (TA) is arranged adjacent to the first region and in an inward side of the light guide (11).
