Abstract
A piezoelectric resonator utilizes a thickness shear vibration mode, which allows for simplification of the manufacturing process, effectively suppresses ripples in the width mode, has superior frequency characteristics and is inexpensive. This piezoelectric resonator includes a pair of vibration electrodes provided on portions of first and second main surfaces, respectively, of a piezoelectric substrate, and a damping member arranged so as to cover a vibrating portion only on one main surface of the piezoelectric resonator and a pair of side surfaces connecting the first and second main surfaces.
