It was found for the first time that the electrical conductivity of Y-substituted Cd2Sb2O7, Cd2(1–x)Y2xSb2O7, with the pyrochlore structure, is larger than at least 3.3 × 10° Scm–1 and the optical band gap of the sample is wider than 3.5 eV. These values indicate that Cd2(1–x)Y2xSb2O7 pyrochlore has a characteristic of a transparent conductor.
