A manufacturing method of spectacle temples is provided to improve and diversify design of the spectacle temples and simply manufacture the spectacle temples at the same time by injection molding the spectacle temples using two materials. A manufacturing method of spectacle temples comprises: forming a grooved portion(11) having a thickness corresponding to a half thickness of the spectacle temples on a bottom mold(10) for first injection molding to form a first formed part(1'); forming a grooved portion(21) on a top mold(20) to form a portion which is not dividingly formed, but is formed to the entire thickness; and configuring a grooved protrusion(22) such that the groove protrusion is protruded to a half thickness or the entire thickness of a core material, wherein the grooved protrusion is formed to form a groove(3) into which the core material is injected at a position corresponding to the center of a dividingly formed portion. |
