Abstract
In an energy-trapping piezoelectric resonator which utilizes a harmonic in a thickness-extensional vibration mode, first and second excitation electrodes are provided partially on both major surfaces of a piezoelectric substrate such that they are opposed to each other on the front and rear surfaces via the piezoelectric substrate. First and second lead electrodes are connected to the first and second excitation electrodes, and first and second terminal electrodes provided along edges of the piezoelectric substrate are connected to the first and second lead electrodes, respectively. A spurious suppressing electrode section is connected to a portion of at least one of the first and second lead electrodes.
