Abstract:
A lens moving apparatus includes a housing; a bobbin disposed in the housing; a coil coupled to the bobbin; a magnet which is disposed in the housing and faces the coil; a base disposed to be spaced apart from the bobbin; a lower elastic member including a first elastic member, a second elastic member, a third elastic member, and a fourth elastic member, which are coupled to the bobbin and disposed on the base; and a sensing coil which is disposed in the housing and generates an induced voltage by an interaction with the coil. A corner of the base and a corner of the housing form a coupling area where the corners are coupled to each other, and the sensing coil includes a portion disposed outside the coupling area.
