PURPOSE: A compact camera module is provided to improve the driving force of a coil by inducing magnetic field. CONSTITUTION: A lens body tube(300) moves up and down due to the interaction of a magnet(400) and the electromagnetic field of a coil(600). The magnet is installed in the outside of the lens body tube. The coil is arranged in the lower part of the magnet. A sub-yoke(520) is arranged in the side of the coil. The sub-yoke induces the magnetic field of the magnet to be orthogonal to the direction of the current flowing in the coil. The sub-yoke induces the magnetic field passes the coil to return to the magnet.
