Abstract
A method of producing an ultrasonic probe may include superimposing an ultrasonic wave receiving organic piezoelectric element layer made of an organic material on an ultrasonic wave transmitting inorganic piezoelectric element layer made of an inorganic material, and polarizing the ultrasonic wave receiving organic piezoelectric element layer and the ultrasonic wave transmitting inorganic piezoelectric element layer on a condition that the ultrasonic wave receiving organic piezoelectric element layer is superimposed on the ultrasonic wave transmitting inorganic piezoelectric element layer.
