Abstract
An ultrasonic probe is configured such that: a piezoelectric element group is housed within a sealed container so as to be rotated and oscillated left and right about a center line that equally divides a plate surface of the piezoelectric element group; and the sealed container is filled with a liquid that serves as an acoustic medium, and in the sealed container there are provided an inlet hole for the liquid as well as an exhaust hole, to the inlet hole there is connected a flexible tube that functions as a diaphragm, and on the flexible tube and the exhaust hole there are respectively provided sealing lids. As a result, there is provided an ultrasonic probe that prevents an occurrence of air bubbles in a liquid that serves as an ultrasonic wave medium, and that realizes excellent ultrasonic characteristics.
