Lens driving device and camera module

The invention provides a lens driving device and an imaging element capable of suppressing occurrence of bad conditions caused by foreign matters due to contact between components. The lens driving device includes a base member, a lens holding member, a driving mechanism that moves the lens holding member relative to the base member, and a stopper portion that restricts rotation of the lens holding member about an optical axis. The base member has a base portion in which an opening is formed, and a fixed-side pedestal portion protruding upward from the base portion. A stopper recess for opening the upper side and the optical axis side is formed in the fixed-side pedestal part. The lens holding member has a cylindrical portion to which the lens body is mounted, and a protruding portion that protrudes outward from the cylindrical portion and enters the stopper recess. In addition, an adhesive foreign matter capturing member is disposed at a portion between the opening in the upper surface of the base portion of
