Patent ID: 8830651

Claim:
A laminated ceramic capacitor comprising: a laminated body comprising dielectric ceramic layers including crystal grains and crystal grain boundaries and internal electrode layers; and external electrodes disposed on a surface of the laminated body electrically connecting to internal electrode layers, wherein the laminated body has a composition comprising, as its main constituent, a perovskite-type compound including Ba, Ca, and Ti, and further containing Mg, R (in which R is at least one member selected from the group consisting of Y, La, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb), and Zr, and the contents of the respective elements in terms of parts by mol are Ca: 3 parts by mol or more and 15 parts by mol or less, Mg: 0.01 parts by mol or more and 0.09 parts by mol or less, R: 2.5 parts by mol or more and 8.4 parts by mol or less, and Zr: 0.05 parts by mol or more and 3.0 parts by mol or less with respect to 100 parts by mol of Ti, and there is Ca at least at the centers of crystal grains.
