Abstract
A piezoelectric/electrostrictive element includes a substrate, an adhesive layer, a first conductive layer, an anchor portion and a second conductive layer. The substrate contains a ceramic as a main component. The substrate has a main surface. The adhesive layer is formed on the main surface of the substrate. The adhesive layer contains a metal oxide as a main component. The first conductive layer is formed on the adhesive layer. The anchor portion is formed on the adhesive layer. The anchor portion is embedded in the conductive layer. The anchor portion contains glass as a main component. The second conductive layer is disposed opposite to the first conductive layer with the substrate located in-between.
