Abstract: The present invention relates to a camera module, the camera module including a base formed at an upper surface of a PCB (Printed Circuit Board) mounted with an image sensor, and formed with an IRCF (Infrared Cut Filter) at a position corresponding to that of the image sensor, a bobbin vertically reciprocatively formed at an upper surface of the base, and having a bobbin screw thread at an upper surface, a lens barrel formed with a lens barrel screw thread at an outer surface for being screw-connected to an interior of the bobbin and mounted with at least one or more lenses, and a foreign object blocking unit formed at a screw-connected portion between the bobbin and the lens barrel to prevent sticky and adhesive foreign objects from being transmitted to an IRCF (Infrared Cut Filter) in the course of screw-connection between the lens barrel and the bobbin.

Abstract: The present invention relates to an imaging lens, the imaging lens including, in an ordered way from an object side, a first lens having a positive (+) refractive power, a second lens having a negative (?) refractive power, a third lens having a positive (+) refractive power, and a fourth lens having a negative (?) refractive power and having a negative (?) refractive power from a lens center to a lens ambience.
