Camera module

A camera module comprising:

• a housing comprising an internal space;
• a carrier accommodated in the housing and being movable relative to the housing in a direction perpendicular to an optical axis;
• a ball member disposed between the housing and the carrier;
• a lens module accommodated in the carrier and movable in an optical axis direction relative to the carrier;
• an elastic unit connected to the carrier and the lens module;
• a driving unit comprising a magnet unit disposed in the carrier and including a plurality of magnets, a first coil unit disposed in the lens module, and a second coil unit disposed in the housing and including a plurality of coils;
• a first position sensor unit disposed to face the magnet unit in a direction perpendicular to the optical axis;
• and
• a second position sensor unit and a third position sensor unit disposed to face the magnet unit in the optical axis direction,
• wherein a magnet facing the second position sensor unit and a magnet facing the third position sensor unit are disposed perpendicular to each other, and
• any one of the second position sensor unit and the third position sensor unit comprises two Hall sensors.
