Piezoelectric device

A piezoelectric device, comprising:

• a piezoelectric element having, on a surface of a piezoelectric body, an exciting electrode and a drawing electrode that is electrically coupled to the exciting electrode and draws an electrode to an external section, and a substrate bonded to the drawing electrode with a metallic brazing material, wherein:
• the piezoelectric element contains a connecting electrode connecting the exciting electrode with the drawing electrode;
• and
• the connecting electrode and/or the exciting electrode contains an underlying layer provided on the surface of the piezoelectric body and a surface layer section provided on a surface of this underlying layer, wherein:
• the underlying layer having a connected portion of the exciting electrode and the drawing electrode, is provided using the metallic brazing material and a metallic material of adverse wettability;
• and
• a portion of the surface layer section is removed in a manner that the connected portion of the exciting electrode and the drawing electrode provided by the surface layer, are separated.
