CERAMIC SINTERED BODY, CERAMIC SUBSTRATE, MOUNTING SUBSTRATE, ELECTRONIC DEVICE, AND METHOD FOR MANUFACTURING CERAMIC SINTERED BODY
A ceramic sintered body includes a ceramic sintered body containing Al2O3 (alumina) and an additive, in which a content of Al2O3 is 94 mass % or greater. The additive contains SiO2 (silica), CaO (calcia), MgO (magnesia), TiO2 (titanium oxide), and Fe2O3 (iron oxide). In the ceramic sintered body, a content of Ti (titanium) in terms of TiO2 is 120 ppm or greater, and a content of Fe (iron) in terms of Fe2O3 is 180 ppm or greater.
