Lens moving device, camera module and optical apparatus

A lens moving device comprising:

• a bobbin;
• a holder member disposed at an outer side of the bobbin;
• a first coil coupled to the bobbin;
• a driving magnet coupled to the holder member and configured to move the first coil through an electromagnetic interaction with the first coil;
• a second coil configured to move the driving magnet;
• a base disposed below the holder member, wherein the second coil is coupled to the base such that the second coil is configured to move the driving magnet through an electromagnetic interaction with the driving magnet, and wherein a printed circuit board with an image sensor is disposed below the base;
• an elastic member configured to elastically connect the bobbin and the holder member;
• a support member configured to elastically connect the holder member and the base;
• a sensing magnet disposed in a sensing magnet reception area formed as a concave groove concavely formed on an outer circumferential surface of the bobbin;
• a location detection sensor disposed on an upper portion of the holder member and configured to sense a location of the sensing magnet;
• and
• a correction magnet disposed on the outer circumferential surface of the bobbin opposite to the sensing magnet reception area of the bobbin;
• wherein the location detection sensor is disposed in an accommodation portion formed in the holder member whereby a portion of the holder member is recessed,
• wherein the sensing magnet is disposed on an upper portion of the bobbin,
• wherein the first coil is arranged below the sensing magnet such that a portion of the bobbin is arranged between the sensing magnet and the first coil,
• wherein the driving magnet is disposed on a lower portion of the holder member facing the first coil, and
• wherein the sensing magnet and the correction magnet are disposed above the first coil and are overlapped with the first coil in a first direction parallel to an optical axis.
