To provide a vibration actuator favorable in drive performance, a manufacturing method for vibration actuators, a lens barrel, and a camera.

The vibration actuator (10) includes: an electromechanical transducing element (13) that transduces electrical energy into mechanical energy; an elastic body (12) that produces an oscillatory wave by excitation of the electromechanical transducing element (13); a resin layer (24) that is formed of conductive thermoplastic resin and bonds the electromechanical transducing element (13) and the elastic body (12) together; and a relative movement member (15) that is brought into contact with the elastic body (12) under pressure and is moved relative to the elastic body (12) by an oscillatory wave.
