Provided is the light guiding member including an incident surface, an exit surface extending in a first direction, a light guiding surface opposed to the exit surface, and being configured to guide light entering the incident surface to the exit surface, a side surface connecting the exit surface and the light guiding surface, and a held portion formed on the side surface. The light guiding surface includes a plurality of deflection portions arrayed in the first direction. At least one of a density or a depth of each of the plurality of deflection portions differs between a first region on the light guiding surface, which corresponds to a region at which the held portion is present in the first direction, and a second region on the light guiding surface adjacent to each of both sides of the first region in the first direction.
