DIELECTRIC COMPOSITION AND MULTILAYER CAPACITOR
To provide a dielectric composition having high reliability and a multilayer capacitor using the same.SOLUTION: One embodiment of the present invention provides a dielectric composition and a multilayer capacitor including the same. The dielectric composition includes a BaTiO3-based main ingredient, a first auxiliary ingredient including rare earth elements, and a second auxiliary ingredient including at least one of Ba and Ca but essentially including Ba. The rare earth elements include Tb and Dy, and when T_RE is a total molar content of the rare earth elements in the first auxiliary ingredient, the first auxiliary ingredient and the second auxiliary ingredient satisfy a molar content condition of 0.40<(Tb/T_RE)×(Ba+Ca)<0.93.SELECTED DRAWING: Figure 1
【課題】高い信頼性を有する誘電体組成物とこれを用いた積層型キャパシタを提供する。【解決手段】本発明の一実施形態は、ＢａＴｉＯ３系主成分と、希土類元素を含む第１副成分と、Ｂａ及びＣａの少なくとも一つを含むが、Ｂａを必須に含む第２副成分を含み、上記希土類元素はＴｂ及びＤｙを含み、上記第１副成分において、上記希土類元素の総モル含有量をＴ＿ＲＥとしたとき、上記第１副成分及び第２副成分は、０．４０＜（Ｔｂ／Ｔ＿ＲＥ）×（Ｂａ＋Ｃａ）＜０．９３のモル含有量の条件を満たす誘電体組成物及びこれを含む積層型キャパシタを提供する。【選択図】図１
