PIEZOELECTRIC LAMINATE, SURFACE ACOUSTIC WAVE DEVICE, THIN-FILM PIEZOELECTRIC RESONATOR, AND PIEZOELECTRIC ACTUATOR |
| 摘要 |
A piezoelectric laminate including a base and a first piezoelectric layer formed above the base and including potassium sodium niobate. The first piezoelectric layer is shown by a compositional formula (KaNa1-a)xNbO3, "a" and "x" in the compositional formula being respectively 0.1<a<1 and 1<=x<=1.2.
