PURPOSE: A mold for producing a meniscus aspheric lens is provided to obtain lenses of uniform shape by preventing the deformation of work pieces even in case of repetitive machining. CONSTITUTION: A mold for producing a meniscus aspheric lens comprises a lower mold(40), an upper mold(30), a lower core(41), and an upper core(31). The upper mold is coupled to the top of the upper core. The lower core is integrally formed in the lower mold. The upper core is integrally formed in the upper mold. When meshing the upper and lower molds, the upper core forms a cavity corresponding to the shape of a meniscus aspherical lens together with the lower core.
