A lens module includes a barrel and a parallelogram-shaped filter. The barrel defines a through hole bounded by an inner circumferential surface thereof. The barrel includes an end surface substantially perpendicular to the inner circumferential surface. The barrel further defines four positioning cutouts extending from the end surface to the inner circumferential surface. The parallelogram-shaped filter includes four corners fixed in the four positioning cutouts of the barrel.
