DIELECTRIC CERAMIC, LAMINATED CERAMIC ELECTRONIC COMPONENT, LAMINATED CERAMIC CAPACITOR, AND METHOD FOR PRODUCING LAMINATED CERAMIC CAPACITOR

摘要

There are provided a dielectric ceramic having large specific resistance and even capacitance characteristic at 150° C., as well as a laminated ceramic electronic component employing such a dielectric ceramic. A ceramic layer includes crystal grains, the ceramic layer containing a perovskite type compound containing Ba, Ca, Ti, and Zr, containing Si, and optionally containing Mn. When the total content of Ti and Zr is 1 molar part, the content of Mn is 0.015 molar part or less, the content of Si is 0.005 molar part or more and less than 0.03 molar part, the molar ratio x of Ca/(Ba+Ca) satisfies 0.05x0.20, and the molar ratio y of Zr/(Ti+Zr) satisfies 0.03y0.18. The crystal grains have an average grain size of less than 130 nm.
