Abstract
An ultrasonic probe provided with an ultrasonic wave-transmitting/receiving element comprising a 1-3 type or 2-2 type composite piezoelectric body exposing a piezoelectric monocrystal from at least one of the faces of the composite piezoelectric body, and an electrode mounted on at least one of the faces of the composite piezoelectric body, wherein the composite piezoelectric body comprises a piezoelectric monocrystal whose electromechanical coupling coefficient ratio k.sub.33 /k.sub.t is 1.6 or more, and a resin whose acoustic impedance Zp is 4.times.10.sup.6 kg/m.sup.2 s or less.
