A vehicular camera module includes a housing that houses an imager assembly and a main circuit board. The imager assembly includes an imager on an imager circuit board, a lens barrel, a lens holder and a flexible ribbon cable extending from the imager circuit board. The main circuit board has first circuitry disposed at a first planar side and second circuitry disposed at a second planar side. An electrical connector at the second planar side connects with an electrical connector of the flexible ribbon cable. The main circuit board is accommodated within front and rear portions of the housing, while the imager is accommodated within the rear portion and is not accommodated within the front portion. The imager views to exterior of the housing via an opening of the upper cover at the rear portion of the housing, and the lens barrel extends through the opening.
