徴とする機械走査型超音波探触子。A mechanical scanning type in which a transducer is placed in a case filled with oil, and the transducer is driven via a motion transmission mechanism by rotation of a rotating shaft whose tip side protrudes into the case and whose peripheral part is sealed with an oil seal. In the ultrasonic probe, a magnetic seal is arranged in parallel with the oil seal at a predetermined distance apart from the oil seal on the rear end side of the rotary shaft in the axial direction of the rotary shaft, and between the magnetic seal and the rotary shaft. A mechanical scanning type ultrasonic probe characterized in that a magnetic fluid is interposed therebetween, and a separation liquid that does not mix with either the oil or the magnetic fluid is sealed between the oil seal and the magnetic seal.
