    摘要： Dielectric ceramic includes dielectric ceramic grains having BaTiO 3 as a major component thereof, a portion of the dielectric ceramic grains having a ferroelectric core and a paraelectric shell into which Mg and a rare earth element are diffused. The shell being located at least on a part of a surface of the core, wherein the shell includes at least two shell portions having different components diffused thereinto. The shell portions can be radially disposed on one another or be in direct contact with the surface of the core.
