中超音波送受波器。 A column-shaped active column made of a piezoelectric material or a magnetostrictive material to which a vibration force is applied; and a bend having an elliptical cross section that is connected to both ends of the active column and encloses the active column and magnifies its vibration displacement. In the flextension type low-frequency underwater ultrasonic transducer comprising a bending shell, the bending shell is coupled to both ends of the active columnar member to amplify the vibration displacement of the active columnar member. A pair of mutually symmetrical first elliptic curve parts having a cross section of one partial elliptic curve, and further expanding the vibration displacement of the first elliptic curve part between the pair of first elliptic curve parts. Formed as a second elliptic curve part having a cross section of a second partial elliptic curve that is symmetrical to each other and different from the first elliptic curve part, and vibrates together with the first elliptic curve part in the same phase as the active columnar material. This is a flextensional type low frequency underwater ultrasonic transducer characterized by:
