Abstract
An image shake correction unit includes a base member, a yoke, a lens holding member, a driving unit, a rotation suppression unit configured to restrict rotation of the lens holding member around an optical axis of the lens unit, and a biasing member configured to bias the lens holding member toward the base member in a direction of the optical axis. The driving unit and the rotation suppression unit are disposed to satisfy a predetermined condition in a case where the image shake correction unit is viewed from the direction of the optical axis. Further, the biasing member has one end provided on the rotation suppression unit and the other end provided on the base member.
