ABSTRACT:
A piezoelectric resonance component includes spacer plates located on both side surfaces of a piezo-resonator so as to form through clearances for allowing vibration of a vibrating part. Case substrates are located on both major surfaces of the piezo-resonator and the spacer plates through spacer frame members for defining clearances for allowing vibration of the vibrating part of the piezo-resonator. Dynamic dampers are located between the vibrating part of the piezo-resonator and ends of a piezoelectric substrate for suppressing vibration received from the vibrating part and for preventing vibration from being transmitted to a holding part.
