1. A lens driver comprising:
a coil that is disposed on a substrate that extends in a first direction and a second direction;
a sensing portion that is disposed to not overlap the coil along a plane formed by an intersection of the first direction and the second direction;
a first magnet that overlaps the coil along a third direction that is perpendicular to the first direction and the second direction; and
a second magnet that overlaps the sensing portion along the third direction,
wherein a total distance from an upper surface of the substrate to a lower surface of the first magnet along the third direction and a total distance from the upper surface of the substrate to a lower surface of the second magnet along the third direction are different from each other.
