Abstract
An upper electrode is provided on one main surface of a piezoelectric layer, and a lower electrode is provided on the other main surface thereof. A vibration section is an area in which the lower electrode, the piezoelectric layer and the upper electrode overlap in a vertical projection direction. Line electrodes for respectively connecting the lower electrode and the upper electrode to input/output electrodes are provided on the one main surface and the other main surface of the piezoelectric layer. The vibration section is placed on (connected to) the substrate via the support section. The support section is provided on an area of the piezoelectric layer excluding the area on which the vibration section is provided and the area on which the input/output electrodes and the line electrodes are provided.
