A camera module includes a camera housing; a lens assembly, part of which is accommodated in the camera housing; and a stopper member coupled to the inside of the camera housing. The lens assembly includes a lens and moves in a direction of an optical axis of the lens inside the camera housing. At least part of the stopper member limits a movement range of the lens assembly in the direction of the optical axis. The stopper member includes a first stopper member to limit the movement range of the lens assembly in a first optical axis direction, and a second stopper member to limit the movement range of the lens assembly in a second optical axis direction opposite to the first optical axis direction. The first and second stopper members are configured to provide damping when the lens assembly makes contact with the first and second stopper members.
