A light blocking layer forming method of a camera module, the method comprising:
- forming a light blocking stamping surface on a substrate;
- contacting a master mold formed with a ring-shaped lug to the light blocking stamping surface;
- forming a light blocking layer by transcribing the light blocking layer on the lug using a surface energy difference;
- and
- forming the ring-shaped light blocking layer on an exposed outermost lens surface by contacting the ring-shaped light blocking layer transcribed on the lug to an outermost lens surface activated by an actuator and by transcribing the light blocking layer to the outermost lens surface using a surface energy difference.
