A lens driving device is provided which includes a housing supporting a magnet; a bobbin having a first coil disposed on the outer peripheral surface thereof and moved by an interaction between the magnet and the first coil; an upper elastic member and a lower elastic member coupled to the bobbin and the housing; and a sensing coil disposed at the housing to be spaced apart from the magnet and generating an induced voltage by an interaction with the first coil, the sensing coil being wound around a side part of the housing so as to rotate in a clockwise direction or in a counterclockwise direction with reference to an optical axis.
