Abstract
A camera module comprises a lens array including at least one lens, a lens accommodating unit having an inner space, in which the lens array is arranged, and an incident hole, and a housing mounted on a circuit board. The housing has 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 has an image area on which light is focused. The image sensor is electrically connected to the circuit board. A filter is disposed between the lens array and the image sensor. The filter includes a transparent medium through which light introduced along the optical axis is transmitted to the image area, and a prevention film for preventing electromagnetic waves generated by the image sensor from being emitted out of the housing.
