To provide a method of manufacturing a wafer level lens, the method manufacturing a wafer level lens having high light-shielding performance and preventing ghost and flare due to reflected light while restraining increase in manufacturing cost; and to provide a wafer level lens and an imaging unit.
This invention relates to a method of manufacturing the wafer level lens having at least one lens module including a substrate and a plurality of lenses formed on the substrate. The method includes steps of: forming a lens on the substrate; applying a black resist layer on the lens surface of the lens and the surface of the substrate; and forming the applied black resist layer in such a pattern that a portion intersecting the optical axis of the lens is open. Thus, the wafer level lens having high light-shielding performance and preventing ghost and flare due to reflected light can be manufactured while increase in manufacturing cost is restrained.
