LAMINATE AND PIEZOELECTRIC/ELECTROSTRICTIVE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a laminate and a piezoelectric/electrostrictive element, capable of increasing adhesive force between an inorganic substrate and a metal film.SOLUTION: A piezoelectric/electrostrictive element 20 including: a piezoelectric body 22; a first electrode 21; and a second electrode 23 is disposed on an inorganic substrate 10. The inorganic substrate 10 includes: a main body part 10a; and a plurality of salients 10b embedded in the first electrode 21. An outer diameter W of the salient 10b becomes smaller as it becomes closer to the main body part 10a.
