Abstract
A piezoelectric resonator formed as a thin parallelepipedic quartz plate whose width is arranged along the electric axis X of the crystal, the length along an axis Y' and the thickness along an axis Z', wherein the axes Y' and Z' form an angle approximately equal to 24.degree. with the mechanical axis Y and the optical axis Z of the crystal, respectively, and the ratio w/l of its width to its length is approximately equal to 0.64.
