A vibration wave driven motor includes a vibration member for generating a vibration wave in response to an applied signal. A contact member includes a contact element which contacts the vibration member. The vibration wave creates relative movement between the vibration member and the contact member, and the surface of the contact member is made of a non-fiber type compound resin having a Rockwell hardness of 80-110 while the vibration member is made of a stainless steel of precipitation.
