Abstract

This invention is to provide a mold for molding an optical element in which eccentricity of an optical insert can be suppressed as much as possible. In order to achieve this object, in a mold for molding an optical element, which molds an optical element having a curved optical surface on at least one surface thereof by injecting and solidifying a molten resin material, a mold member that forms a cavity surface for molding the optical surface includes a plurality of specular optical inserts that divide the optical surface into a plurality of surfaces. Contact surfaces of the divided specular optical inserts which come into contact with each other have grooves extending from the optical surface.
