Abstract
A lens unit composed of different materials includes a base and a lens. A part of a camera module of a different material from the lens is used as the base. The lens of optical resin is directly replicated on the base such that the lens is integrally formed on the base. A camera module is provided with the lens unit. The lens/lenses is/are formed on the single base/multiple bases to form the lens unit/units, using a die whose surface contacting the base slopes in relation to its central axis to allow the base to self-align.
