1. A lens driving device comprising:
a housing;
a bobbin disposed in the housing;
a magnet disposed on the housing;
a first coil disposed on the bobbin and configured to move the bobbin in a first direction by an electromagnetic interaction with the magnet;
a sensing coil disposed on the housing so as to be spaced apart from the magnet and configured to generate an induced voltage by an interaction with the first coil; and
a second coil facing the magnet in the first direction in parallel to an optical axis,
wherein a recess is formed in an outer surface of a side portion of the housing, and the sensing coil is disposed in the recess of the housing.
