Abstract
The purpose of the present invention is to provide an optical unit with camera-shake correction function capable of minimizing the load applied to a movable element from a flexible wiring substrate even when the movable element is oscillated, in order to correct camera shake. In an optical unit provided with a camera-shake correction function, a movable element can be oscillated about an oscillation support point by actuating a drive mechanism for camera-shake correction, and camera shake can therefore be corrected. In a flexible wiring substrate drawn out from the movable element, a folded part folded along the rear end portion of the movable element in the optical axis direction is formed in a drawn-out portion from the movable element, and in the optical axis direction, the oscillation support point is positioned between the surface of the folded part that faces the end part on the other side −Y in the Y-axis direction of the rear end portion of the movable element in the optical axis direction, and the surface that faces toward the rear in the optical axis direction at a fixed part of the flexible wiring substrate with respect to a fixed body.
