Abstract
An optical member includes a light guide body and a light shielding member. The light guide body includes an incident surface on which a light from a blind area is incident, a first reflecting surface configured to reflect the light from the incident surface, a second reflecting surface configured to reflect the light reflected by the first reflecting surface, prisms protruding from the first reflecting surface in a normal direction of the first reflecting surface, and a protruding portion protruding from the first reflecting surface in the normal direction. The light shielding member is in contact with the protruding portion to provide a space between the light shielding member and the first reflecting surface and covers the first reflecting surface to block a light incident toward the first reflecting surface from an outside of the light guide body.
