A method of fabricating an anti-noise earplug having an inner tip serving as a core and an outer tip coupled to the inner tip to surround the inner tip and inserted into an ear includes the steps of: (a) shaping the inner tip; (b) fixing the inner tip to an upper mold for shaping the outer tip; (c) disposing the upper mold to face a lower mold having a cavity for shaping the outer tip; (d) injecting a resin composition for forming the outer tip into the lower mold; (e) pressing down the upper mold to the lower mold; (f) curing the resin composition to couple the outer tip to the inner tip; and (g) separating the upper mold from the lower mold and then separating the earplug, in which the outer tip is coupled to the inner tip as a body, from the lower mold. In fabricating the earplug, the inner tip and the outer tip can be molded in an in-line process, thereby improving the fabrication efficiency.
