An auto-focusing module comprises a lens, an actuator and an external focusing assembly. The lens is a single-focus optical system and assembled in the actuator. The actuator includes an electric focusing element and conductive pins and is hollow in the direction along the optical axis to accommodate the lens therein. The actuator is exteriorly provided with protruding blocks. The external focusing assembly includes a focusing base and a conductive element. The focusing base is provided with inclined surfaces to engage the external protruding blocks of the actuator. The conductive element is electrically connected with the conductive pins of the actuator. By such arrangements, the actuator can drive the lens to move in the direction of the optical axis to realize automatic focusing.
