ABSTRACT:
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.
