Abstract
The invention relates to a double oxide which is transparent and electrically conductive. This double oxide has a defective fluorite crystal structure and is represented by a formula of In.sub.3 Sb.sub.1-X O.sub.7-.delta. where X is in a range of from about -0.2 to about 0.2, and .delta. is in a range of from about -0.5 to about 0.5. The double oxide is good in electric conductivity and high in visible light transmittance, in particular in short wavelength region of visible light, as compared with conventional oxide materials.
