A camera module comprises a main body, a cone disposed in the main body to accommodate a lens, a base joined to the cone, a frame movably disposed on the base, an image detection unit fixed to the frame and moving on the base via the frame, a first circuit board joined to the image detection unit and moving on the base via the image detection unit, a second circuit board disposed on the main body, and a flexible circuit board with one end connected to the first circuit board and the other end connected to the second circuit board. The flexible circuit board has a plurality of slits dividing the flexible circuit board into a plurality of strips. The slits are parallel and extend from the first circuit board to the second circuit board.
