Abstract
A first supporting section provided between a substrate section and a second supporting section. The first supporting section is structured by, e.g., a film formed from a material having a higher acoustic impedance than a piezoelectric body and the substrate section, or a film formed from a material having a smaller Q value than the piezoelectric body and substrate section. By inserting the first supporting section, most vibration from the second supporting section toward the substrate section is reflected, and also a vibration having been transmitted to the substrate section from the second supporting section is prevented from reflecting at the bottom of the substrate sectionand then returning in a direction of the vibration section.
