Beschreibung
Zusammenfassung:	An input portion includes a first electrode and a first deformation portion. An output portion 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. The transmission portion has flexibility, and the flexibility allows the transmission portion to be deformed from a reference state. An input signal is input to the first electrode. The first deformation portion is deformed by the input signal to generate an elastic wave. The transmission portion transmits the elastic wave from the first deformation portion to the second deformation portion. The second deformation portion 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.
