PIEZOELECTRIC LAMINATE, SURFACE ACOUSTIC WAVE ELEMENT, THIN FILM PIEZOELECTRIC RESONATOR, AND A PIEZOELECTRIC ACTUATOR |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a piezoelectric laminate formed on a substrate with a piezoelectric layer composed of potassium sodium niobate.SOLUTION: A piezoelectric laminate 100 includes a substrate 1 and a first piezoelectric layer 3 composed of potassium sodium niobate formed above the substrate 1. The first piezoelectric layer 3 is represented by a composition formula (KNa)NbO, where 0.1<a<1 and 1≤x≤1.2. |
