A vibration wave driving device comprises a vibrator (22) constituted at least of a piezo-electric element (21) and a contact member (20) capable of causing an ellipsoidal movement by synthesis from stationary wave vibrations, and a supporting member (24) for supporting the vibrator (22), for driving a driven member (25) in contact with the contact member (20) of the vibrator (22) by ellipsoidal movement of the vibrator. Furthermore, the vibration wave driving device has a vibration-preventing member (23) attached to a node (Q1, Q2) other than a support portion (2004, 2005, 2006, 2007) of the vibrator (22) among the common nodes of a nodal circle or a nodal line (L1, L2, L3, L4, L5) of the plural stationary wave vibrations excited in the vibrator (22).
