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 terminal rib, a terminal disposed on the terminal rib, and a coating layer disposed on an upper surface of the terminal rib and an upper surface of the terminal;
wherein the coating layer exposes a portion of the upper surface of the terminal, andwherein a length of a boundary line between the coating layer and the portion of the upper surface of the terminal is longer than a width of the terminal.
