摘要：

<P>PROBLEM TO BE SOLVED: To provide an ultrasonic probe having no possibility of conduction failure caused by peeling of an electrode even if a monocrystal forming a piezoelectric body causes chipping when cutting (dicing) it in an array shape, capability of securing reliable conduction, and a high yield in a manufacturing process, a method of manufacturing the same, and an ultrasonic medical image diagnostic device equipped with the ultrasonic probe. <P>SOLUTION: In the ultrasonic probe, an acoustic lens, an acoustic matching layer, an ultrasonic vibrator, and a packing layer are bonded and laminated in this order, the piezoelectric body composing the ultrasonic vibrator is the monocrystal or a crystal having uniaxial orientation, and the electrode is provided only on a layer or a member adjacent to the piezoelectric body. <P>COPYRIGHT: (C)2012,JPO&INPIT
