Summary: | A dielectric ceramic composition including a base material represented by (Ba(1-x)+REx)mTiO(3+x) (here, m is more than or equal to 0.995 and is less than or equal to 1.010, 0.001<x<0.010, and RE is at least one rare earth (RE) atom selected from a group consisting of Dy, Y, Ho, Sm, and Gd) or Bam(Ti+REx)O(3-x) (here, m is more than or equal to 0.995 and is less than or equal to 1.010, 0.001<x<0.010, and RE is at least one RE atom selected from a group consisting of Dy, Y, Ho, Sm, and Gd) as a main component, and a multi-layer ceramic capacitor using the same. In the dielectric ceramic composition, high permittivity (dielectric constant of 1800 or more) and high temperature reliability may be secured by using a RE atom doped/solid-solubilized base material and adding oxides, which are sub-components. |
