ABSTRACT:
A piezoelectric vibration element having a favorable drive level characteristic for miniaturization, and a piezoelectric oscillator. The piezoelectric vibration element includes a base made of a piezoelectric material, a plurality of vibration arms extended from the base, a long groove formed along a longitudinal direction of a main surface of each of the plurality of vibration arms, and an exciting electrode provided inside the long groove. A center position in a width dimension of the long groove is decentered in a minus X-axis direction from a center position of an arm width dimension.
