Claim 9:
10. A lens driving apparatus, comprising:
a holder, comprising an opening hole;
a cover coupled to one side of the holder;
a carrier movably disposed in the cover, and for coupling to a lens;
at least one first magnet arranged in an inner part of the cover;
a coil coupled to the carrier, and facing the first magnet;
at least one second magnet disposed on one end of the carrier which is toward the holder;
a hall sensor for detecting a magnetic field of the at least one second magnet; and
a circuit board, wherein the hall sensor and an imaging element are connected to the circuit board, and the imaging element is for receiving an imaging light of the lens;
wherein the second magnet and the hall sensor are not overlapped with each other in a direction orthogonal to an optical axis of the lens;
wherein a component parallel to the optical axis of the lens of a distance between the hall sensor and the second magnet which is detected by the Hall sensor is d1, a component orthogonal to the optical axis of the lens of the distance between the hall sensor and the second magnet is d2, and the following condition is satisfied:

d1>d2.
