To provide an anti-vibration actuator capable of obtaining a large drive force while avoiding an increase in size. An anti-vibration actuator (10) for moving an image-stabilizing lens (16) within a plane perpendicular to the optical axis thereof, including a fixed portion (12); a movable portion (14) to which the image-stabilizing lens is attached; a movable portion support means (18) for supporting the movable portion to permit translational and rotational movement within a plane parallel to the fixed portion; and first drive means (20a, 22a), second drive means (20b, 22b), and third drive means (20c, 22c) respectively disposed around the image-stabilizing lens for driving the movable portion relative to the fixed portion; whereby the drive force which can be generated by the third drive means differs from the drive forces which can be generated by the first and second drive means.
