A camera module captures an image of an area ahead of a vehicle. A control circuit board performs a recognition process to recognize conditions ahead of the vehicle, and performs at least two vehicle control processes from among a lane departure warning process, a headlight control process, and a forward collision avoidance process. A housing accommodates the camera module and the control circuit board. A bracket fixes the housing to the windshield of the vehicle, and has an opening permitting the housing and the windshield to face each other in a state where the housing is fixed to the windshield via the bracket. A hood covers the camera module. A first thermally conductive member is provided being in contact with the housing and the windshield in the opening formed on the bracket.
