ABSTRACT:
A tubular body having a substantially rectangular cross-section is formed with a plurality of flat plates each having a surface with a light reflecting coating applied thereto. To form the tubular body, the flat plates are disposed in such a manner that the surfaces having the light reflecting coating applied thereto face inward and that an end surface of one of the flat plates at one end is held in contact with the surface of another flat plate. The flat plates are bonded by bonding the end portions thereof with each other on the outer side surfaces of a tubular body so as to form an optical rod.
