The connection part may deform at least partially so that a plurality of acoustic signals radiated from the piezoelectric layer due to the connection part have different magnitudes. In the case of the ultrasonic probe, since the magnitude of the acoustic energy radiated from the center of the ultrasonic probe is larger than the magnitude of the acoustic energy radiated from the side of the ultrasonic probe, the directivity of the ultrasonic signal is improved and a side lobe is decreased. In addition, an apodization effect capable of suppressing overlapping between adjacent phases can be obtained by using a difference in the magnitude of the acoustic energy to be radiated.
