PURPOSE:To effectively give a vibration to any part of a body to be inspected by providing together a vibration applying means for applying the vibration having plural frequency components to the body and a means for allowing a pulse-like ultrasonic wave to be made incident on the body. CONSTITUTION:On the surface of a sample 1, an oscillatory wave transducer 2 and a probe wave transducer 3 are arranged to contact with each other. This oscillating wave transducer 2 is driven by a driving circuit 4, and applies an oscillating wave containing a high frequency component and a low frequency component to the sample 1. The probe wave transducer 3 is connected to an ultrasonic wave transmission/reception circuit 5, and allows a pulse-like ultrasonic wave to be made incident on the sample 1. As a result, in the inside of the sample 1, a large vibration of a low frequency and a minute vibration of a high frequency are generated, a vibration can be given to any part of the inside of the sample 1, and a more accurate tomograph can be obtained. |
