An exemplary lens module includes a number of optical components, a barrel receiving the optical components therein, an image sensor and a holder engaged with the barrel. The holder receives the image sensor therein. The holder has an electromagnetic shielding coating formed thereon. The electromagnetic shielding coating is comprised of a polymeric matrix and a number of carbon nanotubes dispersed in the polymeric matrix and is configured for blocking electromagnetic interference from outside the holder. The lens module can block electromagnetic interference.
