Abstract
A piezoelectric resonator having excellent filter characteristics and effectively suppressing unnecessary ripples and/or spurious components includes first and second excitation electrodes disposed on a first major surface of a piezoelectric substrate, a first common electrode on a second major surface so as to oppose the first and second excitation electrodes with the substrate being located therebetween, and two lead lines extending along portions of longitudinal edges of the piezoelectric substrate. An excitation-lead line is connected to the first and second excitation electrodes which partly overlap a ground-terminal electrode provided on the lower surface with the piezoelectric substrate located therebetween.
