ABSTRACT:
A plastic optical fiber comprising a core and a clad, said core being formed by an amorphous and optically transparent polymer and said clad being formed by a polymer having a refractive index lower than that of the core by at least 0.3%, at least one of the core and the clad being formed by an amorphous and optically transparent polymer containing metal elements and halogen atoms, is low in light loss and excellent in heat resistance.
