Abstract
The lens barrel has an image blur correction function for correcting an image blur, including: a movable member movable in a direction orthogonal to an optical axis while holding a lens and a driving magnet; and a fixed member for positioning the movable member in an optical axis direction and holding a driving coil and a magnetic member, in which: the driving magnet and the magnetic member constitute a driving portion for moving the movable member in the direction orthogonal to the optical axis; and in a plane orthogonal to the optical axis, a width of the magnetic member in a direction orthogonal to a direction of driving the movable member is larger than a width of the driving magnet in the direction orthogonal to the direction of driving the movable member.
