Abstract
A wafer lens array comprising a plurality of lens sections arranged one-dimensionally or two-dimensionally, a substrate section connecting the lens sections, and gap sections, wherein the lens surfaces in the lens section each have one or more curved surfaces; the gap section is a part projecting from outside than the inner edge of the lens section; and the inner surfaces of the gap sections are spread from a side near the lens section to the other side.
