MULTILAYER CERAMIC CAPACITOR
PROBLEM TO BE SOLVED: To provide a multilayer ceramic capacitor excellent in life characteristics and sufficiently suppressed in a leakage current even when the thickness of a dielectric layer thereof is 0.8 μm or less.SOLUTION: A multilayer ceramic capacitor 1 includes a laminate 11 in which internal electrode layers 13 having different polarities different from each other are layered alternately via a dielectric layer 12. The dielectric layer 12 contains a ceramic particle containing BaTiOas a main component. The ceramic particle contains Mo, Mn, rare earthes R, and at least one selected from the group consisting of V and W. The average valence of Mo in the ceramic particle is 4.50-5.50.SELECTED DRAWING: Figure 1
【課題】誘電体層の厚さが０．８μｍ以下でも、寿命特性に優れ、かつリーク電流が十分に抑制された、積層セラミックコンデンサを提供する。【解決手段】極性の異なる内部電極層１３が誘電体層１２を介して交互に積層されてなる積層体１１を備える積層セラミックコンデンサ１である。誘電体層１２は、ＢａＴｉＯ３を主成分とするセラミック粒子を含み、該セラミック粒子は、Ｍｏと、Ｍｎと、希土類Ｒと、Ｖ及びＷからなる群より選ばれる少なくとも一種とを含み、前記セラミック粒子中のＭｏの平均価数が４．５０〜５．５０である。【選択図】図１
