子。 an ultrasonic solid propagation medium, an input transducer with a function of converting an electric signal into an ultrasonic signal, an output transducer with a function of converting an ultrasonic signal into an electric signal, and the ultrasonic wave. In the electrical signal transfer element provided in the ultrasonic solid propagation medium, the backing material has a function of attenuating reflected wave spurious generated by reflection at the interface between the solid propagation medium and each of the transducers. An electric signal transfer element, characterized in that a protective member having an acoustic impedance different from the acoustic impedance of the propagation medium is coated on a reflective surface.
