ABSTRACT:
An oscillatory wave motor, a lens barrel, and a camera system are provided, which have long service lives and which are stable. An oscillatory wave motor includes an oscillator which generates oscillation on an elastic member in accordance with excitation of an electromechanical conversion element, and a relative movement member which is pressurized to make contact with the oscillator and which moves relative to the oscillator in accordance with the oscillation. The oscillatory wave motor has an epoxy resin film formed of silicon beads and an epoxy resin and which is formed on at least one of frictional contact surfaces of the oscillator and the relative movement member.
