摘要

as a vibration wave driving device 25 has the piezoelectric element 20 of the annular containing a plurality of electrodes sandwiched between the installing the piezoelectric material (1) and a piezoelectric material (1) of the annular, a power supply member (8) comprising at least an electric wiring (8a) to supply power to the wavelength of the piezoelectric element, and the element 20 in the annular configured to vibrate by the traveling wave of a ( ), first the elements 20 and a power supply member (8) provided in the first surface. Element 20 has at least two driving areas (15, 16), and 2 arranged between two of the one or more drive area and n / 4 Average annular length, where n is a non-driving region having an odd number, 17 It includes. At least one electrode provided on the first side is arranged over the area 15, 16 and region 17, is electrically connected to the power supply member (8) only in regions 17. ;
