    Abstract: A piezoelectric resonator element includes a piezoelectric substrate formed of an AT-cut quartz crystal substrate in which the thickness direction thereof is a direction parallel to the Y′ axis; and excitation electrodes disposed so as to face vibrating regions on both front and rear principal surfaces of the piezoelectric substrate. The piezoelectric substrate includes a rectangular excitation portion in which sides parallel to the X axis are long sides thereof, and sides parallel to the Z′ axis are short sides thereof; and a peripheral portion having a smaller thickness than the excitation portion and formed around the excitation portion. Each of side surfaces of the excitation portion extending in a direction parallel to the X axis is present in one plane, and each of side surfaces of the excitation portion extending in a direction parallel to the Z′ axis has a step.

    Abstract: A piezoelectric resonator includes: a piezoelectric plate having a vibrating portion surrounded by a peripheral portion; and an excitation electrode on the piezoelectric plate, wherein long sides of the vibrating portion and excitation electrode are parallel to a piezoelectric plate long side. Assuming a piezoelectric plate long side length X, a vibrating portion thickness t, a vibrating portion long side length Mx, an excitation electrode long side length Ex, and a piezoelectric plate flexure vibration wavelength λ, λ/2=(1.332/f)−0.0024 (piezoelectric resonator resonance frequency f), (Mx−Ex)/2=λ/2, Mx/2={(A/2)+(1/4)}λ (where, A is a positive integer), and X≧20t. A protruding portion is disposed on a vibrating portion extension line and parallel to a vibrating portion short side. Assuming a protruding portion length Dx, Dx=(λ/2)×m (where, m is a positive integer). Assuming a distance Sx between the vibrating and protruding portions, Sx=(λ/2)×n±0.1λ (where, n is a positive integer).
