A sputtering target contains Si and C as its major components and includes a texture in which a Si phase continuously exists in a net shape in gaps among SiC crystal grains. An average diameter of the Si phase is controlled to 1000 nm or less. The sputtering target is sputtered in an oxygen-containing gas, thereby depositing an optical thin film containing Si and O as its major components, and a third element other than the major components, a total amount of the third element being within a range from 10 to 2000 ppm.

A ceramics composite member includes a structure in which a first ceramic member and a second ceramic member are integrated with a joint portion. The joint portion has a texture in which a silicon phase having an average diameter of 0.05 μm or more and 10 μm or less is continuously provided in a network form in interstices of silicon carbide particles having an average particle diameter of 0.1 μm or more and 0.1 mm or less.

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.
