Lens driving device havng a movable element and a first column portion configured to limit a range of the movable element

A lens driving device for driving a lens, comprising:

• a base member;
• a movable element arranged to be stacked on the base member in a direction of an optical axis of the lens, and movable with respect to the base member;
• a piezoelectric actuator having a piezoelectric element, and configured to move the movable element in a direction orthogonal to the direction of the optical axis of the lens by expanding and contracting the piezoelectric element;
• a lens carrier arranged to be stacked on the movable element, on an opposite side to a side provided with the base member, in the direction of the optical axis of the lens, the lens carrier being capable of holding the lens;
• a first column portion rising from the base member toward a movable element side, and configured to limit a moving range of the movable element moved by the piezoelectric actuator;
• and
• a case covering the base member so as to accommodate the movable element, the piezoelectric actuator, the lens carrier, and the column portion,
• wherein the first column portion abuts on an inner surface of the case.
