Summary:A MEMS element (1) comprises: a piezoelectric element (100) that includes a piezoelectric film (40) that includes a ferroelectric and vibrates when voltage is applied thereto; and a diode part (200) that is electrically connected to the piezoelectric element (100) in parallel and includes at least one diode (200A, 210, 220). Un élément MEMS (1) comprend : un élément piézoélectrique (100) qui comprend un film piézoélectrique (40), lequel comprend un élément ferroélectrique et vibre lorsqu'une tension lui est appliquée ; et une partie diode (200) électriquement connectée à l'élément piézoélectrique (100) en parallèle et comprenant au moins une diode (200A, 210, 220). MEMS素子(1)は、強誘電体を含み、電圧を印加することで振動する圧電膜(40)を含む圧電素子(100)と、圧電素子(100)と電気的に並列に接続され、少なくとも1つのダイオード(200A,210,220)を含むダイオード部(200)とを備える。
