PIEZOELECTRIC VIBRATING PIECE, PIEZOELECTRIC DEVICE, AND METHOD FOR MANUFACTURING PIEZOELECTRIC DEVICE |
摘要 |
A piezoelectric vibrating piece is to be bonded to and sandwiched between a lid plate and a base plate with an external electrode. The piezoelectric vibrating piece has a first main surface at the lid plate side and a second main surface at the base plate side. The piezoelectric vibrating piece includes an excitation unit, a first excitation electrode, a second excitation electrode, a framing portion, one connecting portion, a first extraction electrode, and a second extraction electrode. The connecting portion includes a planar surface parallel to both the main surfaces and a side face intersecting with the planar surface. The first extraction electrode is extracted via the connecting portion. The second extraction electrode is extracted via the connecting portion. The first extraction electrode is disposed on at least a part of the side face of the connecting portion to be extracted to the framing portion.
