Claim:
1. A camera module, the camera module comprising: a PCB (Printed Circuit Board) mounted with an image sensor; a lens unit installed at an upper side of the PCB, and disposed at a position corresponding to that of the image sensor; an actuator unit comprising a bobbin including a through hole accommodating the lens unit and adjusting a focus of an image; and a flange unit formed on a peripheral surface of the lens unit and protruded from the peripheral surface of the lens unit, wherein a coupling surface of the lens unit is formed as a cylindrical surface on the peripheral surface of the lens unit at a bottom side of the flange unit, wherein the peripheral surface of the lens unit is not formed with a screw thread, wherein an upper portion of the bobbin is coupled with the flange unit of the lens unit, wherein an inner surface of a bottom portion of the bobbin is surface-contacted with the coupling surface of the lens unit, wherein a taper unit is formed on an inner surface of the bobbin between the upper portion of the bobbin and the bottom portion of the bobbin, wherein an outer diameter of the flange unit is longer than an inner diameter of the inner surface of the bottom portion of the bobbin, wherein the flange unit and the taper unit are vertically overlapped with each other, and wherein a bottom end of the lens unit is disposed lower than a bottom end of a coil unit of the actuator unit.
