Lens driving device, and camera module and optical device including same

A lens moving apparatus comprising:

• a housing;
• a bobbin disposed in the housing;
• a first coil disposed on the bobbin;
• a magnet disposed in the housing so as to correspond to the first coil;
• an upper elastic member coupled to an upper portion of the bobbin and to an upper portion of the housing;
• a second coil disposed under the housing so as to correspond to the magnet in an optical-axis direction;
• a circuit board disposed under the second coil;
• an elastic connection portion extending from the circuit board and comprising a coupling portion;
• a support member comprising one end coupled to the upper elastic member and another end coupled to the coupling portion of the elastic connection portion;
• and
• a damper disposed between the elastic connection portion and the circuit board to connect the elastic connection portion to the circuit board,
• wherein the connection portion comprises:
• a first connection portion extending from one region of a corner of the circuit board;
• a second connection portion extending from another region of the corner of the circuit board;
• and
• a third connection portion connecting to at least one of the first connection portion or the second connection portion and connected to the coupling portion.
