Abstract
Disclosed herein is a camera module comprising: a circuit board; a frame coupled to the circuit board; an image sensor on the circuit board; a bobbin on the frame, a plurality of lenses being inside the bobbin; a coil wound on the bobbin, the bobbin moving to two directions based on a current applied to the coil; a magnet configured to interact the coil; and a yoke on the frame, the magnet being at an inner side of the yoke, wherein the bobbin moves to a first direction when a forward current is applied to the coil and to a second direction when a reverse current is applied to the coil.

A camera module comprising:
- a printed circuit board;
- an image sensor disposed on the printed circuit board;
- a frame disposed above the printed circuit board;
- a filter disposed on the frame;
- a yoke comprising an upper plate and a lateral plate extending from the upper plate;
- a bobbin disposed in the yoke;
- a lens barrel coupled to the bobbin;
- a lens coupled to the lens barrel and overlapped with the image sensor in an optical axis direction;
- a coil disposed on the bobbin;
