A lens barrel of a camera module is provided to prevent a tilt of a lens by forming an external protrusion having an upper horizontal plane corresponding to a surface of a lens supporter. A lens barrel includes a barrel(110) and at least one lens(120). The barrel includes a lens supporter(112) formed at a top end of an inside thereof. An external protrusion(122) is formed at an outer surface of the lens. The lens is arranged in an inner hole of the lens barrel. In the lens arranged in a top end of the inner hole of the lens barrel, an upper horizontal plane(122a) of the external protrusion of the lens comes in contact with a lower horizontal plane(112a) of the lens supporter for a center axis of the barrel to coincide with an optical axis of the lens. The lens is a replica lens including a glass lens(124) and a replica layer(126) formed on the glass lens. The external protrusion is formed at an edge of the replica layer.
