A lens module for preventing electromagnetic wave and static interference

The utility model relates to a lens module for resisting electromagnetic wave interference and static interference, which is produced by locating the lens base of the lens module on a preset circuit board, wherein the inside of the lens base is penetrated by a plurality of through holes, the lens base is made of conducting material or by galvanizing the outer surface with a conducting layer, a lens group is located above the lens base, a plurality of identifying members electrically connected with the preset circuit board are respectively positioned at the bottom of the through holes of the lens base and correspond to the lens group provided above the through holes, further an earth portion is equipped on the periphery of the plurality of identifying members and is enabled to form an earth return circuit with the conducting material of the lens base, thereby the aims of raising identification, stability, accuracy and durability of the identifying members to valuable papers, reducing rates of wrong detection a
