Abstract
An image blur correction device includes: a movable frame which is equipped with a lens or an imaging element and has a guide part; a fixed frame having a guide supporting part which movably supports the movable frame by coming into contact with the guide part; and a drive mechanism which drives the movable frame for correcting image blur by moving the movable frame relative to the fixed frame. The fixed frame has magnetic bodies, and the movable frame has urging magnets at positions corresponding to the magnetic bodies. Specifically, the urging magnets use attractive force between the magnets and the magnetic bodies, so as to urge the movable frame in a direction in which the guide part and the guide supporting part come into contact with each other.
