Abstract

PURPOSE:To achieve high output with a small size, by winding up in spiral shape with hollow section at the center for the laminator of piezoelectric high polymer film with electrodes. CONSTITUTION:Piezoelectric high polymer films 1, 1' provided with electrodes 2, 3 in thin film on one side are laminated with the electrodes 2, 3 clipped. Further, this laminator is wound up in spiral shape so that a hollow section 4 is formed at the center.
