Abstract: Even when a condensing lens is not used in combination with a light source, or visible light or infrared light in a short−distance communication is used, unnecessary propagation light does not propagate on a protection film to permit high−quality optical communication. A plastic optical fiber comprising a core (1) and a clad (2) formed by using resin containing appropriate substances, and a protection film (3) formed on the outer periphery of the clad (2) and using hydrocarbon resin, an absorption layer (4) containing pigments (42) for absorbing light of a specified wavelength being formed on the outermost layer of the protection film (3).
