PURPOSE:To provide a plastic optical fiber having a small transmission loss, satisfactorily transmitting the light in a core material, capable of extending the practical fiber length, and effectively allowing a light leak from the side face of the optical fiber. CONSTITUTION:An illuminating plastic optical fiber is constituted of a transparent core material and a sheath material and allows a light leak from the desired portion of the side face of the optical fiber, and the desired portion for a light leak of the optical fiber is made thinner in aperature than the other portion of the optical fiber. |
