Abstract
An ultrasonic probe includes: a plurality of piezoelectric elements separated from each other by a gap; and an acoustic matching layer formed of a rubber elastic material on a surface of each of the plurality of piezoelectric elements. An acoustic impedance of the rubber elastic material is smaller than an acoustic impedance of the piezoelectric elements and larger than an acoustic impedance of a subject. The acoustic velocity of the rubber elastic material has a value of 1650 msec or less.
