The present invention provides an autofocus module including: a supporting base, an electrical focusing element and an conductive element, wherein the supporting base at least accommodates one lens element, the electrical focusing element is disposed at one end of the supporting base so that the electrical focusing element and the lens element are positioned along a common optical lens, and the conductive element is embedded in the supporting base and connected to the electrical focusing element and an external power source respectively. The electrical focusing element obtains power through the conductive element, and by controlling the power magnitude supplied to the electrical focusing element, the focal length thereof can be changed accordingly, thereby carrying out the autofocus operation. |
