Provided is an auto-focusing camera module having a liquid lens. The auto-focusing camera module includes a lens barrel having a liquid lens and a solid lens stacked and disposed therewith; an image sensor for focusing light that is passed through the liquid lens and the solid lens; a substrate provided in a lower end of the lens barrel to electrically mount the image sensor; and a power supply unit fixed integrally in the lens barrel and electrically coupled between the liquid lens and the substrate to apply a power source to the liquid lens. Therefore, the auto-focusing camera module may be useful to control its focus to coincide with high pixels and high performances of the camera module, manufacture a small final product by lowering the entire height of the camera module, enhancing the productivity of the camera module by employing a simple liquid lens to simplify an assembly structure of the liquid lens that is in contact with the substrate, and reduce the manufacturing cost.
