PURPOSE: A camera module is provided to confirm a starting point from which a bobbin moves, thereby performing a precise auto-focusing control. CONSTITUTION: A camera module comprises a PCB(Printed Circuit Board)(10), a base(20), a bobbin(30), one or more pairs of sensing electrodes(100), and conductive parts. An image sensor is mounted on the PCB. The base is installed on the upper part of the PCB, and an infrared cutoff filter is installed in a position corresponding to the image sensor. The bobbin is installed on the upper part of the base to be moved up and down. The sensing electrodes are installed on a surface of the base facing the bobbin. The conductive parts are arranged on a surface of the bobbin facing the sensing electrodes. |
