DIELECTRIC COMPOSITION AND LAMINATED CERAMIC ELECTRONIC COMPONENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a dielectric composition and a laminated ceramic electronic component using the same.SOLUTION: There is provided a dielectric composition including dielectric grains having a perovskite structure represented by ABO, wherein a part of the dielectric grains has a core-shell structure, the core has an average length of 250 nm or less, and dielectric grains satisfying that the ratio of the average length of the core to the average length of the dielectric grains is less than 0.8 are 50% or more of the whole dielectric grains having the core-shell structure. A laminated ceramic electronic component using the dielectric composition has an effect capable of securing excellent reliability and a high dielectric constant.
