| 简介 |
A dielectric ceramic composition includes at least dielectric particles having a core-shell structure and segregation particles, a concentration of a rare earth compound in the segregation particle is twice or more than an average concentration of the rare earth compound in a shell part of the dielectric particle having the core-shell structure, an area occupied by the segregation particles is 0.1 to 1.1%, when a maximum particle size of the segregation particle is defined as rbmax, a minimum particle size of the segregation particle is defined as rbmin, and an average particle size of the dielectric particle having the core-shell structure is defined as ra, a relation of rbmax/ra≦2.00 and rbmin/ra≧0.25 is satisfied, and the segregation particles substantially do not include Mg. |
