Beschreibung
Zusammenfassung:	An input includes a first electrode and a first deformation portion. An output includes a second electrode and a second deformation portion. A transmission portion enables transmission of an elastic wave from the first deformation portion to the transmission portion and transmission of an elastic wave from the transmission portion to the second deformation portion. In operation, an input signal is input to the first electrode that deforms the first deformation portion to generate an elastic wave. The transmission portion transmits the elastic wave from the first deformation portion to the second deformation portion that is deformed by the elastic wave to generate an output signal to the second electrode. The detection unit detects a deformation amount from the reference state of the transmission portion based on the output signal.
