    • A vibration type driving apparatus includes a vibrating member configured to simultaneously generate a plurality of standing wave vibrations to cause an elliptic motion on surfaces located at nodes of the standing wave vibration, a driving unit formed on the surface located at the node to perform the elliptic motion, and a moving member configured to contact the driving unit and to be driven by the elliptic motion. The driving unit protrudes from a surface of the vibrating member, and includes a first driving unit and a second driving unit that are formed to sandwich the moving member in a perpendicular direction to the surface. The first driving unit and the second driving unit are located at the nodes that are separated by odd-number times a half-wave length of the standing wave vibration, and located where the directions of the elliptic motions are opposite to each other.
