Claim 14:
15. A lens driving device, comprising:
a base;
a holder member disposed on the base;
a bobbin disposed in the holder member and configured to move in an optical axis direction;
a first coil disposed on the bobbin;
a magnet disposed on the holder member and facing the first coil;
a second coil disposed on the base and facing the magnet;
an elastic member connecting the holder member and the bobbin; and
a detection sensor disposed on the bobbin,
wherein the detection sensor is configured to sense a movement of the bobbin in the optical axis direction,
wherein the detection sensor is disposed on an upper portion of the bobbin,
wherein the first coil is disposed on a lower portion of the bobbin,
wherein an outer lateral surface of the detection sensor is overlapped with the first coil in the optical axis direction, and
wherein the detection sensor is overlapped with an upper portion of the magnet in a direction perpendicular to the optical axis direction in an initial state where electric power is not supplied to the first coil, and
wherein the first coil is overlapped with a lower portion of the magnet in the direction perpendicular to the optical axis direction in the initial state.
