Lens mounting element and its manufacturing method

摘要

There is provided an optical element which can be handled with ease and mounted on a supporting means for supporting it with high precision and efficiency in the course of manufacturing it, and also there is provided a method for manufacturing such an optical element as described above. A lens element 100 is an optical element which is mounted on a supporting substrate provided with a groove for mounting the lens element. The lens element 100 includes a handling portion 120, a side wall 162a which are brought into contact with the groove for mounting use, and a lens portion 180a.
