| Abstract | To suppress the deterioration of moisture resistance and heat resistance of a multilayer ceramic capacitor by suppressing the abnormal grain growth of dielectric particles constituting a dielectric layer.SOLUTION: In a multilayer ceramic capacitor 100, each of a plurality of internal electrode layers contains Ni, and the average grain boundary segregation amount of Ni in each of first and second side margin portions S1 and 2 is larger than the average grain boundary segregation amount of Ni in a portion located at an inner layer portion C of a plurality of dielectric layers 140.SELECTED DRAWING: Figure 3
【課題】誘電体層を構成する誘電体粒子の異常な粒成長を抑制することにより、積層セラミックコンデンサの耐湿性および耐熱性の低下を抑制する。【解決手段】積層セラミックコンデンサ１００であって、複数の内部電極層の各々はＮｉを含有しており、第１，２サイドマージン部Ｓ１、２の各々におけるＮｉの平均粒界偏析量は、複数の誘電体層１４０のうち内層部Ｃに位置する部分におけるＮｉの平均粒界偏析量より多い。【選択図】図３ |
