Abstract
There is provided an imaging lens including: a transparent substrate; an upper lens disposed on a top of the transparent substrate; and a lower lens disposed on a bottom of the transparent substrate to correspond to the upper lens, wherein one of the upper and lower lenses includes a lens element and a partition wall formed higher than the lens element to surround the lens element. Also, there is provided a method of manufacturing the same. In the imaging lens, the partition wall is replicated together with the lens element on one or both surfaces of the transparent substrate. The partition wall is formed higher than the lens element and has a flat top surface. Therefore, when another lens element is replicated on an opposite surface of the transparent substrate, the previously replicated lens element is prevented from deformation.
