Abstract

A plastic optical fiber 1 comprises: a plastic optical fiber body 2; and a coloring material 3 that covers the peripheral surface of the plastic optical fiber body. The coloring material 3 is made of a cured product of a curable composition containing: an active energy ray curable multi-functional acrylate; and a colorant. The reaction rate of a vinyl group of the active energy ray curable multi-functional acrylate of the coloring material 3 is 85% or more.
