PURPOSE: A camera module is provided to increase the sensing reliability of a lens barrel driving position by sensing the lens barrel driving position and to enable a sensor to measure the distance between lines of a reflective plate. CONSTITUTION: A lens collects an external image. A reflective plate(14) is formed in a plurality of lines. A penetration hole exposes a lens barrel(10) which is driven by a driving unit. A case(20) covers the lens barrel. A sensor measures the distance between two lines. The sensing reliability of a driving location of a lens barrel is increased by measuring the distance between lines which are formed in the reflective plate.
