Abstract:
A camera module includes a lens unit including one or more lenses, wherein at least some of the one or more lenses are movable along a path corresponding to optical axes of the one or more lenses, and a driving unit to move the at least some lenses along the path. The driving unit includes a magnet physically connected with the at least some lenses, a coil to form a magnetic field such that the magnet moves along the path, and a magnetic substance disposed on one surface of the coil opposite to another surface of the coil, which is adjacent to the magnet. The magnetic substance adapts the at least some lenses, which are physically connected with the magnet, to a specified position of the path by using magnetic force between the magnet and the magnetic substance, which is formed as the coil approaches the magnet.
