<p>Disclosed is an ultrasonic probe using a compound piezoelectric material made of piezoelectric ceramic and organic polymer. On one principal plane of the compound piezoelectric material (1), electrodes 14) and electric terminals (7) conducting to these electrodes (4) are formed, and these electrodes (4) and electric terminals (7) are divided into a plurality. On the other principal plane of the compound piezoelectric material (1), a common electrode (5) is provided, and an acoustic matching layer (10) is mounted on it either intact or divided in correspondence to the divided electrodes (4). By using part of the compound piezoelectric material (1) as the electric terminal take-out portion (14), the mechanical strength of the electric terminal take-out portion (14) can be improved, which is particularly preferable for the ultrasonic probe driven at high frequonoy.</p> |
