Abstract: A mold for an optical component is provided in which a first tapered surface is provided in a first mold while a second tapered surface is provided in a second mold. In the mold for the optical component, a curved surface distance which is a distance between a first mold curved surface and a second mold curved surface is greater than a lens thickness which is a distance between a first lens surface and a second lens surface in a state where the second tapered surface is contact with the first tapered surface. Moreover, the second tapered surface moves to a position where the curved surface distance is equal to the lens thickness, to elastically transform the first mold and fit onto the first tapered surface.
