Provided is a method for producing an imaging lens unit having stable and highly accurate thickness dimensions and fB, the method being one that prevents a shift in lens and aperture positions and suppresses optical surface deformation. It is possible to integrate aperture units (15, 16) with a glass substrate (11) and resin layers (12, 13), because the imaging lens unit is the type of wafer level lens provided with a glass substrate (11) and resin layers (12, 13) supported by the glass substrate (11). By integrating with the aperture unit (15), it is possible to support a lens (10) with the periphery of optical surfaces (12d, 13e), and position the lens (10) inside a cavity (CA). As a result, it is possible to produce a lens unit (100) capable of suppressing deformation of the optical surfaces (12d, 13e) while preserving the accuracy of the lens (10). Herein, the aperture units (15, 16) are integrated with the glass substrate (11) and the lens layers (12, 13) in advance, and it is possible to definitively prevent a shift in the lens (10) and aperture unit (15, 16) positions, irrespective of the state of formation of a holder member (40). |
