An ultrasonic includes: a piezoelectric layer; an absorbing layer disposed at a lower portion of the piezoelectric layer, configured to absorb an acoustic signal; and a connection part disposed between the piezoelectric layer and the absorbing layer. 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.

Ultrasonic probe

Disclosed herein is a multi-row ultrasonic probe of which a manufacturing failure rate can be decreased. The ultrasonic probe includes a piezoelectric layer configured to generate ultrasonic waves, a sound layer provided on a rear side of the piezoelectric layer, a flexible printed circuit board provided on a rear side of the sound layer, and a sound absorption layer configured to absorb the ultrasonic waves generated by the piezoelectric layer and propagating toward a rear surface of the ultrasonic probe, the sound absorption layer being provided on a rear surface of the flexible printed circuit board. The piezoelectric layer includes a kerf configured to divide the piezoelectric layer in a direction of elevation. The sound layer includes a funnel extending in a direction extending from a front side of the sound layer to the rear side of the sound layer to divide the sound layer.
