发明名称 STACKED PIEZOELECTRIC ELEMENT, MANUFACTURING METHOD THEREOF AND VIBRATION WAVE DRIVING APPARATUS
摘要 A stacked piezoelectric element comprising that can suppress periodic damping on miniaturization of a vibration wave motor and improve its performance. A stacked piezoelectric element comprises piezoelectric layers and electrode layers alternately stacked to have a shape of a cylinder. The electrode layers are divided into a plurality of electrode layer regions along a circumferential surface of the shape of a cylinder.
