| Zusammenfassung: | An energy-trap type piezoelectric resonator utilizes a fundamental wave of a thickness shear vibration mode and includes resonance electrodes provided on both main surfaces of a substantially rectangular piezoelectric plate so as to face each other with the piezoelectric plate disposed therebetween. An energy trap vibration portion including a portion of the piezoelectric plate where the resonance electrodes overlap each other is asymmetrical with respect to the center in the longitudinal direction of the piezoelectric plate. |
