| 简介 |
A dielectric ceramic that includes multiple crystal grains, each of the multiple crystal grains having an interface, a barium titanate (BaTiO3)-based compound as a main component thereof, and a rare earth element. The dielectric ceramic has a cross-section in which the multiple crystal grains has a concentration varying region, a high concentration region, and a low concentration region. The concentration varying region has an RE/Ti ratio differing by 3% or more. The high concentration region has an RE/Ti ratio of 5% to 20%. The low concentration region has an RE/Ti ratio of 0% to 2%. |
