Abstract: Disclosed herein is a camera module. The camera module includes: a lens barrel with a built-in lens collecting external images; a housing that has a receiving space in which the lens barrel is received; a driving part that is configured to include a magnet and a coil and provides a first driving force that drives the lens barrel upward and a second driving force that drives the lens barrel downward by an electromagnetic force that is generated from the magnet and the coil; a guide ball that is provided between the lens barrel and the housing and guides the motion of the lens barrel; and a position detection part that senses the position of the lens barrel, wherein the driving part drives the lens barrel upward and downward so that a preload part that provides preload returning the lens barrel to its initial position is not required.
