[Table 1] * The unit of surface roughness is angstrom, Ra is the center line average roughness, and Rmax is the maximum height. In addition, the expression "no defect" in the surface observation column in the table means that "there is no defect on the polished surface,"
It is judged that the smoothness is inferior to that described as “good”.
