A lens element 1 is formed by making use of an optical substrate, and
includes
a lens portion 2, an edge portion 6 in the form of a circular arc
provided along the circumference of the lens portion 2, and handling portion
4 which is integrated with the lens portion 2 and the edge portion
6 as well and extends with a width wider than that of the lens portion 2.
The handling portion 4 can be caught and held by chucking vacuum suction
and so forth. The lens element 1 can be handled by catching the handling
portion 4 without directly touching the lens element 1, and thus
the lens element 1 is neither damaged nor contaminated, and stably handled
with ease.
