It relates to a camera module for sensing the position of a touch object that touches the touch surface of the optical touch screen. The camera module and one or more lenses, and a converting unit, and an image sensor optical path. The lens is formed to the vertical angle of view in the vertical direction of the touch surface is smaller than the horizontal angle of view in the horizontal direction on the touch surface. It reflects the collected light through the optical path conversion unit lens in the direction perpendicular to the touch surface. The image sensor is disposed in a direction parallel to the touch surface to receive the reflected light through the optical path conversion portion at the rear of the lens.
