Vibration wave drive device, stator for a vibration wave motor, vibration wave motor, driving control system, optical apparatus, and manufacturing method of a vibration wave driving device

摘要: A vibration wave drive device (25) includes an annular piezoelectric element (20) including a material (1) and multiple electrodes provided sandwiching the (1), being configured to vibrate by traveling of wavelength λ; power feeding member (8) at least electric wire (8a) for supplying (20), first surface (20). The two driving regions (15, 16), non-driving region (17) arranged between has average length nλ/4, n odd number. At one electrode on is across 16) (17), electrically connected only in (17).
