Lens driving apparatus, camera module, and optical apparatus

A lens driving device comprising:

• a base;
• a housing disposed on the base;
• a bobbin disposed in the housing;
• a first coil disposed on the bobbin;
• a first magnet disposed on the housing and facing the first coil;
• a first board disposed on the base and comprising a second coil facing the first magnet;
• an elastic member connecting the housing and the bobbin;
• a support member electrically connecting the elastic member and the first board;
• a second magnet disposed on the bobbin;
• a second board;
• and
• a Hall sensor disposed on the second board and configured to sense the second magnet,
• wherein the Hall sensor comprises a sensing part configured to sense a magnetic field,
• wherein the Hail sensor comprises first and second surfaces opposite to each other, third and fourth surfaces connecting the first and second surfaces and opposite to each other, and fifth and sixth surfaces connecting the first and second surfaces and opposite to each other,
• wherein the Hall sensor is coupled to a first surface of the second board,
• wherein the first surface of the Hall sensor faces the first surface of the second board, and
• wherein a distance between the fifth surface and the sixth surface of the Hall sensor is greater than a distance between the third surface and the fourth surface of the Hall sensor.
