PURPOSE: A camera module is provided to couple a protrusion unit of a lower edge portion to a stepped groove unit of a circuit board. CONSTITUTION: An image sensor(130) is installed at an upper portion of a circuit board(140), and converts an image received through a lens barrel(110) into an electric signal. A stepped groove unit(141) is formed at an upper edge of the circuit board, and a housing(120) encloses the lens barrel. The housing is formed to correspond to the location and size of the stepped groove unit. The housing is coupled to the stepped groove unit, and a protrusion unit(121) is formed at the lower edge portion of the housing.
