A camera actuator is configured to include: a fixed-side member; a movable-side member disposed separated from the fixed-side member in a direction orthogonal to a light axis, the movable-side member holding a lens unit; a first lens drive actuator that displaces the movable-side member in at least a prescribed direction; an elastic support member that extends in the direction orthogonal to the light axis, and supports the movable-side member in relation to the fixed-side member so as to allow the displacement in at least the prescribed direction; and a damping member that is disposed between the movable-side member or a member fixed to the movable-side member, and the fixed-side member or a member fixed to the fixed-side member.
