1. A lens moving apparatus comprising:
a housing;
a bobbin disposed inside the housing;
a coil coupled to the bobbin;
a magnet disposed on the housing so as to face the coil;
a base disposed so as to be spaced apart from the bobbin;
a lower elastic member coupled to the bobbin and comprising a first elastic member, a second elastic member, a third elastic member, and a fourth elastic member, wherein the first to fourth elastic members are disposed on the base; and
a sensing coil disposed on the housing so as to generate an induction voltage resulting from interaction with the coil,
wherein a corner of the base and a corner of the housing form a coupling region in which the two corners are coupled to each other,
wherein the sensing coil comprises a portion disposed outside the coupling region, and
wherein the sensing coil comprises a portion that is in contact with an outer surface of the coupling region and overlaps the coupling region in a direction perpendicular to an optical axis.
