PROBLEM TO BE SOLVED: To provide a driver of a vibration actuator which can be made compact while reducing the influence of a step-up section on other parts, and to provide an actuator device including the same, a lens-barrel and a camera.SOLUTION: A driver 34S of a vibration actuator 10 includes: step-up sections 43A, 43B which step up the voltage supplied from a power supply 51 and output it to the vibration actuator 10; a switching section 55 for adjusting the voltage supply from the power supply 51 to the step-up sections 43A, 43B; and a control section 52 for controlling the operation of the switching section 55. The switching section 55 and the control section 52 are held on the same holding substrate 50, and the step-up sections 43A, 43B are located at positions different from that of the holding substrate 50. |
