COMPOSITE MOLDED LENS, METHOD FOR MANUFACTURING SAME, MOLDING DIE AND IMAGING MODULE

摘要

The purpose of the present invention is to improve the bond between a lens body and a lens frame. In this composite molded lens (10), an injection-molded lens frame (15) is integrally formed on a press-molded lens body (14). The lens body (14) comprises a lens part (12), and a flange part (13) surrounding the lens part (12). Eight protrusions (16) are radially formed on the upper surface of the flange (13). The height of the protrusions (16) increases toward the peripheral side of the flange part (13). Recessed parts (18) are formed on the outer peripheral end face of the flange (13) at positions extending from the protrusions (16). The recessed parts (18) improve the torsional strength of the bonding surface, and thereby increase the bonding strength.
