Dielectric ceramics and dielectric resonator
The present inventions provides a dielectric ceramic comprising an oxide containing, as a metal element, at least a rare earth element (Ln), Al, M (M is Ca and/or Sr) and Ti, and at least part of the oxide of Al being present as a crystal phase of beta - Al2O3 and/or θ-Al2O3, thereby having a high epsilon r, high Q value and a small temperature coefficient of resonance frequency in a high frequency region.
