| 简介 |
Provided is a laminated ceramic capacitor having excellent lifetime characteristics in a high-temperature loading test. It includes a laminated body including a plurality of stacked dielectric layers including crystal grain and crystal grain boundaries, and a plurality of internal electrodes and external electrodes. The laminated body contains, as its main constituent, a perovskite-type compound containing Ba and Ti and optionally Ca, and further contains a rare-earth element R, and Mn, Mg, V, and Si With respect to 100 parts by mol the Ti, the total parts by mol content (100×m) of Ba and Ca is 0.950≦m<1.000, the contents in terms of parts by mol is 0.3≦R≦2.5, 0.05≦Mn≦0.5, 0.5≦Mg≦2.0, 0.05≦V≦0.25, 0.5≦Si≦3.0, and further, the molar ratio x of Ca/(Ba+Ca) is 0≦x≦0.01, and the existence of the rare-earth element R in a position of 4 nm inner from a surface of the crystal grain is 20% or more. |
