Abstract
A piezoelectric/electrostrictive element has a piezoelectric body, a first electrode, a second electrode and a glass layer. The piezoelectric body is formed in a thin film-shape. The piezoelectric body has a first main surface and a second main surface. The first electrode is disposed on the first main surface of the piezoelectric body. The first electrode has an electrode side surface configured to be connected with the first main surface. The second electrode is disposed on the second main surface of the piezoelectric body. The glass layer is continuously formed on the first main surface and the electrode side surface. The glass layer containing glass as a principal constituent. The glass layer is isolated from the side surface of the piezoelectric body.
