Abstract: A camera device includes a first lens unit concentrating light incident from a front side; a liquid lens unit disposed on a rear side of the first lens unit and controlling an optical path of light by adjusting a curvature of the liquid lens unit according to an electrical signal; a second lens unit disposed on a rear side of the liquid lens unit; an image sensor on which light passing through the second lens unit forms an image; and a flexible printed circuit board (FPCB) transferring the electrical signal to the liquid lens unit. Further, the liquid lens unit includes a first region allowing light, which is to form the image on the image sensor, to be transmitted therethrough and a second region surrounding the first region. In addition the FPCB is disposed in the second region and overlaps the liquid lens unit in a thickness direction.
