Abstract
The lens drive device is equipped with a first supporting body that holds the lens and is movable in the direction of the optical axis, a second supporting body that holds the first supporting body, a fixed body that holds the second supporting body in a manner enabling movement in directions that are roughly orthogonal to the optical axis direction, a first drive mechanism for driving the first supporting body, a second drive mechanism for driving the second supporting body in a first direction, and a third drive mechanism for driving the second supporting body in a second direction. The first supporting body is supported by the second supporting body by means of first supporting members (8, 9), which are formed from an elastic material; and the second supporting body is supported by the fixed body by means of second supporting members, which are formed from an elastic material.
