Abstract
PURPOSE:To simplify the manufacturing process as well as realize manufacture of a large-size transducer, by forming one of the two electrodes holding the high molecular film between into the electrode pattern and then applying the voltage between the both electrodes to give the piezoelectric property to the high molecular film. CONSTITUTION:Back electrode/back reflecting plate 8 formed into the desired electrode pattern is formed on the surface of supporter 7, and then divided electrodes A1, A2, A3... are formed by burying insulator 9 between patterns. Thus uniform and common surface electrode 11 is formed on the surface of high molecular film 10 to which the polling process is not given yet, and the back surface of film 10 are adhered onto electrode 8. Then the high voltage is applied between electrodes 8 and 11 to perform polling process. As a result, the piezoelectric property is secured to high molecular film 13 at the area between the pattern of electrode 8 and electrode 11, but no piezoelectric property is given to the high molecular film at the area between insulator 9 and electrode 11. Accordingly, the manufacturing process can be simplified, and a large-size transducer can be obtained by using the high molecular film of a large area.
