Abstract
An optical device has a reflecting mirror using a particle-dispersed silicon material including silicon carbide and silicon. The reflecting mirror includes a plurality of segments joined to each other by reaction sintering. Producing the segments is easy in comparison with that of a reflecting mirror of one piece. Accordingly, it is possible to reduce probability of breakage of the segments and to shorten process time of production of a reflecting mirror.
