A plurality of prisms extending in one direction are provided on one principal surface of the optical member in regions on both sides when divided at a virtual plane that includes a reference axis. The plurality of prisms include reflecting prisms that reflect light from a light source that is disposed virtually on the reference axis and emit this light from the optical member.
