  • Patent number: 8682151
    Abstract: Disclosed is an optical unit with a shake correction function which is capable of suppressing interference with swinging of a movable module due to the rigidity of a wiring material and a repelling force generated when the wiring material is deformed, even when the wiring material is extended from the movable module. The optical unit uses a flexible wiring board as the wiring material for electrically interconnecting the movable module and outside. In the flexible wiring board, the connecting portion of a movable-side connecting section and an extending unit is provided, in the optical axis direction, on a side where the swing center of the movable module is positioned with respect to the position of the center of supporting a spring member to the movable module. The swing center, the connecting portion, and a fixed-side connecting section are at the same position in the optical axis direction.
