ABSTRACT:
In a vibration wave motor wherein a member provided with a composite resin layer providing a contact surface with respect to a vibration member for generating a travelling vibration wave is brought into pressure contact with the vibration member, whereby the vibration member and the member pressure-contacting therewith are moved relative to each other by friction driving with the aid of the travelling vibration wave generated in the vibration member, the composite resin layer is formed of a composite resin composed of a thermosetting resin, for example, an aromatic polyimide resin, as a base material, and a friction regulating agent and, if required, a non-fiber type wear resistance improving agent blended with the base material.
