The present invention relates to a vibration wave driving apparatus including: a vibration member which has an electro-mechanical energy conversion element having a plurality of electrode regions that are fixed to an elastic member and polarized in the same direction, and which generates a travelling wave that is obtained by synthesizing a plurality of standing waves different in phase on a surface of the elastic member by supplying an ac signal to the electro-mechanical energy conversion element; and a moving member which is in contact with the vibration member and driven by the travelling wave. The vibration wave driving apparatus of the present invention is characterized in that a plurality of wiring members are connected to a plurality of electrode regions of the electro-mechanical energy conversion element, and that wiring members used for generating standing waves having the same phase among the plurality of wiring members are arranged at intervals integer times the wavelength of the standing waves having the same phase. |
