Abstract
A vehicular camera module includes (i) a lens holder formed of a first material, (ii) a lens barrel accommodating a lens and formed of a second material, (iii) an imager printed circuit board having an imager, and (iv) a processor circuit board having an image processor. The imager printed circuit board is attached at the lens holder with the imager aligned with the lens accommodated in the lens barrel. The processor printed circuit board has circuitry that is electrically connected to circuitry of the imager printed circuit board. The coefficient of thermal expansion of the second material forming the lens barrel is lower than the coefficient of thermal expansion of the first material forming the lens holder. Circuitry of the vehicular camera module includes connecting elements that are configured to electrically connect to a wire harness of a vehicle equipped with the vehicular camera module.
