PURPOSE: A camera module for a mobile device is provided to easily correct a posture of a lens barrel when a defect by assembling tolerance of the lens, thereby satisfactorily correcting resolution. CONSTITUTION: A holder unit(120) is installed on a PCB(Printed Circuit Board) in order to cover an image sensor installed on the PCB. A housing(140) is installed on the upper part of the holder unit and includes a permanent magnet generating a magnetic field along with the inner wall. A lens assembly(130) includes a coil on the outer surface to be operated upward and downward by electromagnetic forces formed between the magnetic field of the permanent magnet. The lens assembly transmits an external image to the image sensor and includes a lens barrel moving upward and downward. A correction screw(150) is combined on the lens assembly in order to control slope of the lens barrel.
