Patent ID: 8587871

Claim:
A wafer lens comprising: a glass substrate; a first resin part which is made of a curable resin and formed on one surface of the glass substrate; and a second resin part which is made of a curable resin and formed on another surface of the glass substrate, wherein each of the first and the second resin parts comprises a single lens part formed within a range of an optically effective surface and at least one of the first and the second resin parts comprises a non-lens part formed out of the range of the optically effective surface, said non-lens part having a different shape from the lens part, wherein the single lens part is formed by cutting a wafer lens laminate, which comprises a glass substrate and two resin layers having a plurality of lens parts, into each lens part, and wherein the shapes of the lens parts of the first resin part and the second resin part are different from each other, and wherein a volume of the resin of the first resin part after the cutting and a volume of the resin of the second resin part after the cutting satisfy a condition of an expression (3), 0.6 ≦Vwa/Vwb≦ 2.1 (3) wherein “Vwa” indicates a volume of a resin on an object side and “Vwb” indicates a volume of a resin on an image side.
