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 to face the first mover on a side surface of the first mover;
• a stator positioned to face a lower side of the second mover to move the second mover and having a through-hole corresponding to the lens unit formed in a center thereof;
• and
• a base supporting the stator and the second mover and having a hollow hole corresponding to a 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,
• wherein the coil member includes:
• a substrate including a first surface and a second surface opposite to the first surface and including a hole;
• a circuit pattern disposed on at least one of the first surface and the second surface and including a wiring pattern, a plating pattern, and a dummy pattern;
• and
• a protective layer disposed on the substrate while surrounding the circuit pattern,
• wherein the protective layer includes a first protective layer disposed on the first surface;
• and a second protective layer disposed on the second surface,
• wherein the substrate includes a first edge disposed outside the substrate and a second edge surrounding the hole,
• wherein the substrate includes a 1-1 region and a 1-2 region adjacent to the first edge,
• wherein the 1-1 region is disposed between the first edge and the 1-2 region,
• wherein a 1-1 protective layer is disposed on the first surface of the 1-1 region,
• wherein a 1-2 protective layer is disposed on the first surface of the 1-2 region,
• wherein a thickness deviation of the 1-1 protective layer is 0.1 μm or less.
