PURPOSE:To obtain an underwater transmitter-receiver of wave reception integrated type sound source structure by which the performance of the underwater transmitter is improved and the measurement device is made small in size and light in weight with respect to the underwater transmitter-receiver integrated with the underwater transmitter and the underwater receiver as the measurement equipment when a reflection capability of a sample in water is measured by the pulse method. CONSTITUTION:A high polymer piezoelectric member 4 used for receiving a sound wave is mounted onto an acoustic radiation face 1A of an underwater transmitter-receiver containing an electroacoustic transducing element (laminated piezoelectric ceramic 2), and the transmitter comprising the acoustic radiation face 1A and the receiver comprising the relevant high polymer piezoelectric member 4 are polymerized on the same face. |
