A camera module for a vehicular vision system includes a lens barrel having a lens, a front camera housing portion configured to receive an imager PCB therein, and a rear camera housing portion mated with a rear portion of the front camera housing. The imager PCB is disposed at the lens barrel with the imager optically aligned with the lens. A thermal element is disposed between the front camera housing portion and the imager PCB. The thermal element (i) has a coefficient of thermal expansion (CTE) element of 10 ppm/° C. or less or (ii) has its temperature controlled via a thermoelectric device of said camera module. Circuitry of the camera module is electrically connected to the imager PCB and is electrically connected to electrical connecting elements that are configured to electrically connect to a wire harness of the vehicle.
