Claim:
1. A lens moving unit, the lens moving unit comprising: a housing; a bobbin disposed inside the housing; a driving magnet disposed on the housing; a coil unit disposed on the bobbin and facing the driving magnet; a support member coupled with the housing and the bobbin that movably supports the bobbin along an optical axis; a sensing magnet disposed on the bobbin; a position detection sensor configured to detect a position of the sensing magnet; a correction magnet disposed on the bobbin at a side opposite to the sensing magnet; and a circuit substrate mounted with the position detection sensor and comprising a plurality of terminals disposed on a bottom end thereof; wherein the housing comprises first and second lateral surfaces opposite to each other, and third and fourth lateral surfaces disposed between the first and second lateral surfaces and opposite to each other; wherein the driving magnet comprises a first magnet disposed on the first lateral surface of the housing and a second magnet disposed on the second lateral surface of the housing; wherein the driving magnet is not disposed on the third and fourth lateral surfaces of the housing; wherein the sensing magnet faces the third lateral surface of the housing, and the correction magnet faces the fourth lateral surface of the housing; and wherein the plurality of terminals of the circuit substrate is connected to a PCB (Printed Circuit Board) mounted with an image sensor.
