Summary:PURPOSE: A compact camera module is provided to induce a magnetic field generated in a magnet in a coil direction, thereby increasing driving power. CONSTITUTION: A magnet(400) is mounted on the outside of a lens barrel. A coil(600) is arranged in a lower part of the magnet. The lens barrel moves up/down by interaction between an electromagnetic field when power is applied to the coil and a magnetic field of the magnet. A yoke(500) for inducing the magnetic field in the coil direction is mounted on the outside of the magnet. The bottom of the yoke is arranged on an upper side than the bottom of the magnet.
