    It was initially found that CdSb2O6, in which a small part of the Cd ions was substituted with Y ions, has characteristics of a transparent conductor. The electrical conductivity at room temperature of the Y-substituted CdSb2O6 ceramic was larger, by at least 1×100 S cm-1, while that of the nonsubstituted CdSb2O6 was smaller than 10-5 S cm -1. The optical band gap of CdSb2O6 was found to be larger than 4.1 eV by the measurements of diffuse reflectance spectra.
