PROBLEM TO BE SOLVED: To provide a piezoelectric oscillation element capable of reducing influence of deformation of an element mounting member on characteristics of the piezoelectric oscillation element.SOLUTION: In an oscillation element 9, a crystal piece 15 comprises a plate-like body part 21, and a pair of frame parts 23 extending and bending from a periphery of the body part 21 in a plan view. The oscillation element 9 further includes a pair of excitation electrodes 17 located on both principal surfaces of the body part 21, and a pair of wirings 19 connected to the pair of excitation electrodes 17 and extending along the pair of frame parts 23 on a surface of the pair of frame parts 23.SELECTED DRAWING: Figure 2 |
