Abstract
The shapes of reflecting parts in a hermetically sealed container are inclined to prevent generation of an unnecessary echo. In a short-axis oscillating ultrasonic probe, a piezoelectric element group arranged along a long-axis direction and having an acoustic lens on an ultrasonic wave transmitting/receiving surface, is provided on a rotary holding table housed in a hermetically sealed container. An ultrasonic wave transmitted and received to/from the ultrasonic wave transmitting/receiving surface of the piezoelectric element group is mechanically scanned in the short-axis direction of the piezoelectric element group by rotating and oscillating the rotary holding table in the short-axis direction, and a liquid serving as an acoustic medium is filled in the hermetically sealed container.
