Abstract

PURPOSE:To adapt for large and continuous mass production of bimorphs by exposing one end of a conductive film interposed between high polymer films from the bonded surfaces of the films and using it as the electrode terminal of internal pressure electrodes when forming a bimorph through bonding the even number of the high molecular films. CONSTITUTION:Conductive films 2a, 2b are coated on both sides of a high molecular film 1 polarized to become piezoelectric and made of polyvinylidene fluoride resin or the like. The piezoelectric films 1, 1' thus formed are interposed with a conductive film 3 therebetween and bonded with adhesive 5. At this time the film 3 is provided not on the entire surface therebetween, the end of the film 3 is projected from the bonded surfaces, and the end is used as the exposed electrode terminal 4 of the internal pressure electrode. Thus, the termial 4 is readily formed, and soft high molecular piezoelectric film 1 may not be scratched.
