ABSTRACT:
A chip-type piezoelectric resonance component is prepared by bonding spacer plates to side portions of an energy trap piezoelectric resonator. The resonator includes a piezoelectric resonance unit coupled with dynamic dampers vibrating for suppressing vibration as it is propagated, with the vibration being suppressed through a phenomenon of the dynamic dampers. Case members are pasted onto upper and lower portions of an element plate through sheet-type adhesives which define spaces for allowing vibration and prevent vibration of the vibrating portions from being hindered.
