Abstract:
A method for manufacturing, by means of molding, an optical fiber fixing member having a plurality of optical fiber engagement grooves for positioning and fixing optical fibers, wherein said method for manufacturing an optical fiber fixing member is characterized in that a preform is pressed by a mold provided with convexities and concavities corresponding to said optical fiber engagement grooves and the peaks between the optical fiber engagement grooves such that the preform is forced into the concavities of said mold, the shape of the convexities of said mold is transferred to the preform, and optical fiber engagement grooves whose surfaces are mold transfer surfaces are formed; andthe molding material is pressure-molded such that the material fills the concavities of said mold only partially, a state is maintained in which the shape of the bottom portions of the concavities in said mold is not transferred, and peaks are formed between the optical fiber engagement grooves such that the surfaces thereof are free surfaces.
