Abstract:
1. A method for producing a wafer lens which includes: a substrate which is transparent and includes a front surface and a back surface; an alignment mark formed on one surface of the front surface and the back surface of the substrate; a first stop member including a plurality of light transmitting sections, arranged on the other surface of the front and back surface of the substrate; a plurality of first lens sections formed of a curable resin, on the one surface of the substrate; and a plurality second lens sections formed of a curable resin, on the other surface of the substrate, the method comprising: an alignment mark forming step of forming the alignment mark on the substrate; a first lens section forming step of forming the first lens sections by molding a curable resin arranged at an area between the substrate and a first mold for molding the first lens sections, under a condition that the first mold is positioned with respect to the alignment mark; a first stop member forming step of forming the first stop member on the substrate; and a second lens section forming step of forming the second lens sections by molding a curable resin arranged at an area between the substrate where the first stop member is formed and a second mold for molding the second lens sections, under a condition that the second mold is positioned with respect to the alignment mark, wherein the first stop member is formed so as not to prevent positioning of the second mold with respect to the alignment mark.
