PROBLEM TO BE SOLVED: To provide a piezoelectric device in which oscillation of a piezoelectric vibration piece can be suppressed when subjected to impact, while suppressing malfunction, damage, or removal from a supporter or a lead of the piezoelectric vibration piece. ! SOLUTION: In a piezoelectric device 10 having two leads 30 penetrating a base 20, and two supporters 40 attached to the leads 30, respectively, and holding the piezoelectric device 10, at least one supporter 40 includes plate-like attachment parts 41a, 42a having a curved or folding cross section perpendicular to the longitudinal direction, and being attached to the leads 30, and flexures 41b, 42b formed by bending a portion between the attachment parts 41a, 42a and the holding parts 41c, 42c for holding the piezoelectric device 10 into crank shape. The linear parts 41c, 42c of the supporter 40 including the holding portions 41d, 42d are formed to have a rigidity smaller than that at the part other than the linear part 41c. ! COPYRIGHT: |
