An ultrasonic probe includes an ultrasonic transmitting/receiving element which uses a piezoelectric member constituted by a solid-solution based single crystal of zinc lead niobate-lead titanate, so that low-frequency driving can be achieved, the thickness of the piezoelectric member in the direction of vibration can be decreased, matching with a transmitting/receiving circuit can be easily made, and the sensitivity can be improved. The ultrasonic probe includes an ultrasonic transmitting/receiving element having a piezoelectric member constituted by a solid-solution based single crystal of zinc lead niobate-lead titanate and a pair of electrodes formed on an ultrasonic transmitting/receiving surface of the piezoelectric member and a surface opposite to the transmitting/receiving surface, respectively.
An ultrasonic probe comprising an ultrasonic transmitting/receiving element having a piezoelectric member consisting of a solid-solution based single crystal of zinc lead niobate-lead titanate, and a pair of electrodes formed on an ultrasonic transmitting/receiving flat surface of said piezoelectric member and a surface opposite to said transmitting/receiving flat surface, respectively.
An array-type ultrasonic probe in which a plurality of ultrasonic transmitting/receiving elements having a piezoelectric member consisting of a single crystal and a pair of electrodes formed on an ultrasonic transmitting/receiving surface of said piezoelectric member and a surface opposite to said transmitting/receiving surface are aligned, wherein
An ultrasonic transducer comprising a piezoelectric member having two flat surfaces and consisting of a solid-solution based single crystal of zinc lead niobate-lead titanate represented by a formula:
