Abstract: The object of the present invention is to provide a plastic image fiber having a small optical transmission loss. The plastic image fiber comprises N (where N is an integer equal to or greater than 2) number of cores which are disposed within a cladding. The each of the cores has an index of reflection that continuously changes at a peripheral part of the core. The index of reflection at the peripheral part on a center side of the core is greater than an index of reflection at the peripheral part on a cladding side.
