Claim:
A camera module comprising: a lens array including at least one lens; a lens accommodating unit having an inner space defined therein such that the lens array is arranged along an optical axis in the inner space and an incident hole formed at the center of the front surface thereof; a housing mounted on the upper surface of a circuit board, the housing having a counter-engagement part engaged with an engagement part formed at the lens accommodating unit such that the lens accommodating unit is moved in the direction of the optical axis; an image sensor having an image area on which light passing through the lens array is focused, the image sensor being electrically connected to the circuit board such that the image focused on the image area is transmitted to the circuit board; and a filter disposed between the lens array and the image sensor, the filter including a transparent medium through which light introduced along the optical axis is directly transmitted to the image area of the image sensor, and a prevention film for preventing electromagnetic waves generated by the image sensor disposed in the housing from being emitted out of the housing; wherein the engagement part of the lens accommodating unit is a male thread part formed at the outer circumferential surface of the lens accommodating unit; and wherein the counter-engagement part of the housing is a female threaded part formed at the inner hole of the housing.
