PROBLEM TO BE SOLVED: To provide a plastic optical fiber for a vehicle, which is lightweight and excellent in thermal resistance, cold resistance, oil resistance or chemical resistance or the like. SOLUTION: This is a plastic optical fiber which is connected to an information system device such as in formation equipment installed on a vehicle, a control system device for controlling a system such as an engine system of a vehicle, and a vehicle body system device such as illumination light, and this plastic optical fiber is made by being drawn after a core material has been formed into a molten material of crystalline perfluoro resin, and is the one for vehicle use characterized in that the perfluoro resin layer having a refractive index smaller than the core material is formed as the clad.
