Abstract
A resin-coupled lens has a resin layer on at least one surface of the lens and has a light-shielding membrane, wherein the edge surface of the outermost perimeter of the resin layer is covered by the light shielding membrane. A production method for the resin-coupled lens includes a resin layer formation process that forms a resin layer on at least one surface of the base material of the lens, a light-shielding membrane formation process that forms a light-shielding membrane on the edge surface of the outermost perimeter of the resin layer by applying a light-shielding coating, and a reflection-preventing membrane formation processes that forms a reflection-preventing membrane at least on the surface of the resin layer.
