发明名称 積層セラミックコンデンサ及び積層セラミックコンデンサの製造方法
摘要 <p>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.</p>
