Lens driving device, camera module and optical instrument

A optical instrument comprising:

• a main body;
• a dual camera module disposed in the main body and configured to photograph an image of a subject;
• and
• a display unit disposed in the main body and outputting an image photographed by the dual camera module,
• wherein the dual camera module includes a first camera module and a second camera module including a second side that faces a first side of the first camera module,
• wherein the first camera module comprises:
• a housing;
• a bobbin disposed inside the housing;
• a coil disposed on the outer circumferential surface of the bobbin;
• and
• two magnets, facing each other, that are arranged at a side of the housing in the direction perpendicular to the first side of the first camera module, so as to face the coil,
• wherein each of the two magnets comprises:
• an upper surface;
• a lower surface;
• an inner surface facing the coil;
• an outer surface disposed on the reverse side to the inner surface;
• and
• two side surfaces connecting the inner surface and the outer surface,
• wherein a depressed part is provided on the side surface of the magnet, among the two side surfaces of the magnet, that is disposed on the first side of the first camera module, the depressed part being formed by recessing a portion of the side surface of the magnet,
• wherein the area of the inner surface of the magnet is smaller than the area of the outer surface of the magnet, and
• wherein the magnet is disposed biased toward a center line (X) of the side of housing.
