For this purpose, an average surface roughness Ra of at least one surface of the SiC wafer is set to be substantially equivalent to a film thickness of a film to be deposited on an Si wafer to be measured.

More concretely, the surface roughness is set to be about 400 times as large as the average surface roughness of a product Si wafer, Ra being preferably set to be 0.08 ?m or less.
