Abstract
A ceramics substrate includes: a substrate body; an electric conductor layer that is built in the substrate body; and a via that is built in the substrate body to be electrically connected to the electric conductor layer. The substrate body is made of ceramics containing aluminum oxide. The via is made of a fired body of an electric conductor paste. The electric conductor paste contains molybdenum as a main component and further contains nickel oxide, aluminum oxide, and silicon dioxide.
