Abstract:
A laminated ceramic capacitor that includes a laminated body including dielectric ceramic layers having crystal grains and crystal grain boundaries, and including internal electrode layers. An external electrode is formed on a surface of the laminated body, and is electrically connected to the internal electrode layers exposed at the surface of the laminated body. The laminated body has a composition including a calcium zirconate based perovskite-type compound as a main constituent, and further including Mn, Sr, and Si. When the laminated body is dissolved, the Si contained therein is 0.1 parts by mol or more and 10 parts by mol or less with respect to 100 parts by mol of Zr, and the molar ratio of Mn to Sr is 0.3 or more and 3.2 or less.
