Summary:PURPOSE: A manufacturing method of optical fiber having a coupled microball lens is provided to simplify the manufacturing steps and to lower a manufacturing cost by forming a plurality of optical fibers having recessive holes on end portions thereof and then coupling the microball lens with the recessive holes. CONSTITUTION: An etching stopper layer is formed on an end portion except for a region of a terminal of an optical fiber(20). A recessive hole is formed on an end portion of the optical fiber where the etching protection layer is not formed. An adhesion material is injected into the recessive hole formed on the end portion of the optical fiber. A microball lens(24) is coupled with the recessive hole where the adhesion material is injected. The etching stopper layer is either one of a silicon nitride(Si3N4) layer or a gold(Au) layer.
