Abstract
A dielectric ceramic including a perovskite compound represented by the general formula {(BaCaSn)(TiZr)O} as a primary component in which the x, y, z, and m satisfy 0.02≦x≦0.20, 0.02≦y≦0.20, 0≦z≦0.05, and 0.99≦m≦1.1 and is processed by a thermal treatment at a low oxygen partial pressure of 1.0×10to 1.0×10MPa. Accordingly, there are provided a dielectric ceramic which can be stably used in a high-temperature atmosphere without degrading dielectric properties, properties of which can be easily adjusted, and which generates no electrode breakage even when ceramic layers and conductive films are co-fired, and a ceramic electronic element, such as a multilayer ceramic capacitor, which uses the above dielectric ceramic.
