1. A lens moving apparatus comprising:
- a housing;
a bobbin disposed in the housing;
a first coil disposed on the bobbin;
a magnet disposed on the housing;
a base disposed below the bobbin; and
a circuit board disposed on the base;
wherein the circuit board comprises;
a body disposed on an upper surface of the base;
a bent portion bent from the body and disposed on an outer side surface of the base;
a terminal disposed on the bent portion; and
a coating layer disposed on an upper surface of the bent portion and an upper surface of the terminal;
wherein a boundary line between the coating layer and the upper surface of the terminal comprises a first line, a second line, and an edge where the first line and the second line meet.wherein the edge is closer to a first end of the bent portion contacting the body than to the second end of the bent portion opposite to the first end of the bent portion.

Abstract
Embodiments provide a lens moving apparatus including a bobbin including a first coil disposed on an outer circumferential surface thereof, a housing provided with first and second magnets for moving the bobbin by interaction with the first coil, upper and lower elastic members each coupled to both the bobbin and the housing, and a first position sensor for detecting a sum of intensities of magnetic fields of the first and second magnets, wherein the first position sensor is disposed in a space between the first magnet and the second magnet when the bobbin is disposed at an initial position.
