A base polymer is mixed with a non-polymerizable compound having a higher refractive index to form a fiber material. This material is continuously transformed into a fiber in a fiber-preparing unit. The fiber is dipped in diffusion tanks containing monomer substances so as to diffuse these substances into the fiber, and cured in a heater so as to polymerize these substances. By alternatingly repeating this procedure, the monomer substances and the non-polymerizable compound are diffused in the fiber and form a graded refractive index. Next, the fiber is drawn, coated with a cladding and coiled. This method can be performed with a high running ratio, minimizing the necessity of scaling-up of the facilities when the production is increased, and easily confers a desired index grading on the fiber. Likewise, the method allow continued manufacturing of a graded refractive index plastic optical-fiber with a desired length and of constant quality.
