    • There is provided a resonator having a piezoelectric ceramic resonator which has excellent free-fall resistance. The resonator comprises a piezoelectric ceramic resonator 2 with a vibrating electrode formed, and a substrate 3 which supports the piezoelectric ceramic resonator 2, wherein the piezoelectric ceramic resonator 2 satisfies the condition of U≧0.88×H+20.28, wherein U=maximum elastic energy (kJ/m3) per unit volume, and H=drop height (m) (H>1). The present invention can be applied to a resonator 1, wherein the substrate 3 has terminal electrodes 31, 32, and the piezoelectric ceramic resonator 2 is in electrical continuity with the vibrating electrode and is supported on the substrate 3 at both ends via a conductive stator 4.
