Image stabilizing coil member and camera module comprising same

A camera module, comprising:

• a first mover disposed on a side surface of a lens unit to move the lens unit;
• a second mover positioned on a side surface of the first mover to face the first mover;
• a stator positioned opposite to a lower side of the second mover to move the second mover, and having a through-hole corresponding to the lens unit formed at a center thereof;
• and
• a base supporting the stator and the second mover, and having a hollow hole corresponding to the through-hole of the second mover formed in a center thereof,
• wherein the stator includes a circuit board and a coil member disposed on the circuit board, and
• wherein the coil member includes:
• a substrate including an upper surface and a lower surface opposite to the upper surface;
• a first coil electrode disposed on the upper surface of the substrate and including a first pattern electrode;
• and
• an upper dummy electrode disposed on the upper surface of the substrate and not electrically connected to the first pattern electrode,
• wherein the first pattern electrode is a coil pattern formed by rotating in one direction on the upper surface of the substrate,
• wherein the upper dummy electrode includes;
• a first inner pattern disposed inside the first pattern electrode and surrounded by the first pattern electrode, and
• a first outer pattern disposed outside the first pattern electrode.
