Abstract: A camera module is provided, the camera module comprising: a bobbin; a coil arranged at the bobbin; a housing disposed at an inside of the bobbin; a magnet arranged at the housing, to face the bobbin; a rib formed at an inside to be extended from a first lateral wall of the housing to a second lateral wall adjacent to the first lateral wall; and a first adhesive groove formed by a part of a lower surface of the rib being recessed to accommodate an adhesive. The camera module has an advantageous effect in that the magnet may be prevented from being removed from the magnet accommodating portion of the housing, even when external force is applied to the camera module.
