<p>The purpose of the present invention is to provide a method for manufacturing wafer lenses, wherein even if the outer diameters of lens sections are not uniform, interference between the outer circumferential portions of the lens sections and spacers can be eliminated with a small space. An adhesive (106) is hardened in a state wherein a constant interval (X) is kept between a substrate (101) and a spacer (105) without having the substrate and the spacer abut on each other, thereby preventing a second lens element (12) and the spacer (105) from interfering with each other when the wafer lenses are laminated, even if the outer diameters of the second lens elements (12) on the first and the second wafer lenses (100, 200) are not uniform. Consequently, a trouble of having the spacer (105) in contact with and placed over the outer circumferential portion (12b) of the second lens element (12) can be eliminated. Furthermore, pitches between the lenses can be reduced compared with the case where buffer regions are provided in first and second molding dies (41, 42), i.e., transfer molding dies for forming the first and the second lens elements (11, 12), and cost of the first and the second molding dies (41, 42) can be reduced.</p> |
