摘要：

An acoustic transducer 56 has a first transducer 56A which transmits an acoustic primary wave having two frequency components, and a second transducer 56B which, in order to receive a reflected wave of an acoustic secondary wave generated with propagation of the acoustic primary wave, is disposed so that a region for receiving the reflected wave is superimposed on the first transducer 56A as seen along the direction of transmission of the acoustic primary wave.
