Abstract
An auto-focus driving structure for installing a lens has an optical axis. The auto-focus driving structure comprises a main body, a lens retainer, and a driving unit. The lens retainer is movably disposed in the main body. The driving unit includes a coil circuit board and a magnetic group. The coil circuit board has a plurality of printed coils. The plurality of printed coils corresponds to the position of the magnetic group, thus the lens retainer can be selectively moved with respect to a bottom portion of the main body through the driving unit.
