Disclosed is an ultrasonic probe having an organism contact portion that is shaped for use along a comparatively large curvature and can easily be used while closely contacting an organism, and that has an adequately reduced size. According to the technique of the invention, a first cylinder pulley 5, secured to a probe casing 7, an arm 16, secured to a motor spindle 17 that is extended through a first pulley, and a second cylinder pulley 8, rotatably arranged on the opposite side, are coupled together by a wire 6. The second pulley is equipped with a slider shaft 14 that is arranged, in an extensible manner, by a slider bearing 15. The slider shaft is quipped with a roller 10 that contacts a guide rail 12 of the probe casing, and an ultrasonic element 2 is attached to the distal end of the slider shaft to provide the telescopic structure for the slider shaft. In this manner, the size of a scanning mechanism, for oscillating the ultrasonic element along a large curvature, is reduced.
