Beschreibung
Zusammenfassung:	According to one embodiment, an ultrasonic probe, in which a plurality of piezoelectric vibrators are arrayed in both of an azimuth direction and an elevation direction, includes a piezoelectric body configured to have a piezoelectric effect; and a matching layer configured to be laminated in an ultrasonic radiation direction of the piezoelectric body. The matching layer is divided in the azimuth direction without being divided in the elevation direction. The piezoelectric body is divided into plural parts in both of the azimuth direction and the elevation direction in such a manner that each of the plural parts of the piezoelectric body forms each of the plurality of piezoelectric vibrators.
