Zusammenfassung:	The ultrasonic probe according to a present embodiment includes a piezoelectric vibrator and an acoustic lens. The piezoelectric vibrator is configured to transmit and receive an ultrasonic wave. The acoustic lens is provided on an ultrasonic-wave transmission/reception side. The acoustic lens is formed in such a manner that a surface shape of each of end regions located on both sides of a central region of a surface of the acoustic lens is formed to have a curvature different from a curvature of a surface shape of the central region of the surface of the acoustic lens.
