Abstract
Provided is an acoustic lens applied to an ultrasound probe and forming an ultrasound beam by focusing ultrasound transmitted from a piezoelectric transducer, in which: an ultrasound radiation surface of the acoustic lens includes: a first area that is located in a lens center portion and forms a focal point at a position corresponding to a deep portion of the ultrasound beam; and a second area that is located on a lens outer side of the first area and forms a focal point at a position corresponding to a shallow portion of the ultrasound beam, and a focal depth formed by a lens portion of each position of the first area and the second area draws a profile that becomes continuously shallow from a side of the lens center portion to the lens outer side.
