摘要：
A plastic molding for use in an optical device, a method of producing the molding by injection molding, and an apparatus for practicing the method are disclosed. Only a part of a molding expected to sink is surely caused to sink while, e.g., a mirror surface is surely transferred to a desired part of the molding.
