Abstract

A method of manufacturing an ultrasonic probe includes the steps of forming electrodes on two surfaces of a piezoelectric single crystal made of a complex perovskite compound and then adhering the piezoelectric single crystal on a backing material, dicing the piezoelectric single crystal to form an arrayed piezoelectric single-crystal transducer, and poling the arrayed piezoelectric single-crystal transducer in the electric field of 0.5 to 2 kV/mm at a temperature of 80.degree. C. or less.
