Piezoelectric thin-film element and a manufacturing method thereof |
摘要 |
To provide a piezoelectric thin-film element small in leak current between electrode metal films and its manufacturing method are presented, the piezoelectric thin-film element comprises at least one unit laminated body composed of a piezoelectric thin-film having mutually facing first surface and second surface, a first electrode metal film on the first surface, and a second electrode metal film on the second surface, in which an electrode separation surface composed of a piezoelectric thin-film surface parallel to the first surface is provided between the first electrode metal film and second electrode metal film.
