Piezoelectric vibrating devices and methods for manufacturing same |
摘要 |
<p>An exemplary piezoelectric device includes a base having a first connection electrode electrically connected to an external electrode. A second connection electrode is connected to the first connection electrode on a first main surface of a supporting member affixed to the base. A third connection electrode, formed on a second main surface of the supporting member, is electrically connected to the second connection electrode. A piezoelectric vibrating piece is affixed to the supporting member by application of an adhesive applied to the third connection electrode. The piezoelectric vibrating piece and includes excitation electrodes. A convexity is located and extends in a designated direction relative to the third connection electrode to prevent applied adhesive from spreading beyond a designated area of the piezoelectric vibrating piece.</p> |
