Abstract
A die which can press-mold an accurate glass microoptical element such as a grating repetitively can be manufactured easily by adhering a thin film, having an inverse shape of the master of a micro-optical element, on the top flat plane of a hard base body and by forming a protective layer thereon. The die having an inverse shape of the master can press-mold glass repetitively. By press-molding glass with the die, a large number of reliable glass micro-optical elements of the same shape as the master can be produced at a low cost.
