Claim 18:
19. A lens moving apparatus comprising:
a first circuit board comprising a second coil and a plurality of first terminals;
a housing disposed on the first circuit board;
a bobbin disposed in the housing;
a first coil and a first magnet configured to move the bobbin in an optical axis direction;
an elastic member connecting the bobbin and the housing;
a damping member disposed on the housing;
a second magnet disposed on the bobbin; and
a position sensor disposed to be overlapped with the second magnet in a direction perpendicular to the optical axis direction,
wherein the first circuit board comprises:
a first region on which the second coil is formed;
a second region in which the plurality of first terminals are formed;
a third region disposed between the first region and the second region and comprising a first hole,
wherein the second magnet comprises:
a first magnet unit disposed on an upper portion of a side surface of the bobbin; and
a second magnet unit symmetrically disposed with the first magnet unit,

wherein a maximum diameter of the first hole in a first direction is greater than a shortest distance from the first hole to an outermost side of the third region in the first direction, and the first direction is perpendicular to the optical axis direction and in parallel to the third region, and
wherein an upper surface of the first magnet unit is positioned higher than the first coil.
