Abstract
A vibration wave motor includes a stator with an upper surface at which is generated a travelling vibration, a rotor with a lower surface rotatably mounted on the upper surface of the stator, and an urging device for developing a frictional force between the upper surface of the stator and the lower surface of the rotor. A sheet member is attached to either the upper surface of the stator or the lower surface of the rotor and the sheet member includes a base member having ultra heat-resistant properties, a fluorine-contained resin and a filler in the form of fibers.
