1. A micro-optic device comprising a mirror and one or more structures other than the mirror each formed of a single crystal silicon layer, wherein
the single crystal silicon layer has a top surface representing (100) silicon crystal plane or (110) silicon crystal plane and has recesses or channels with sidewall surfaces substantially perpendicular to the top surface;
every surface of the mirror and the one or more structures other than the mirror is formed either by a respective sidewall surface or a surface which is parallel to the top surface;
the mirror has a side surface which represents (100) silicon crystal plane or (111) silicon crystal plane and is substantially perpendicular to the top surface, and has unevenness less than that of other sidewall surfaces not representing (100) silicon crystal plane or (111) silicon crystal plane; and
the side surface has a metal coating film forming a reflective surface.
