4. The camera apparatus according to claim 1 , wherein

the camera apparatus comprises one of the plural types of camera modules whose shapes are different from each other whereby the inclination angle in the vertical direction of the optical axis is changed, in a state where the camera apparatus is mounted on the windshield, to configure at least part of the adjustment structure.

5. The camera apparatus according to claim 1 , wherein

the camera apparatus comprises one of the plural types of brackets whose shapes are different from each other whereby the inclination angle in the vertical direction of the optical axis is changed, in a state where the camera apparatus is mounted on the windshield, to configure at least part of the adjustment structure.

6. The camera apparatus according to claim 1 , wherein

the camera module includes a holder holding the lens and a camera board on which an image sensor is mounted, and

the holder and the camera board have shapes whose relative position is adjusted in a state where the holder and the camera board are joined to each other, and are fixed to each other with an adhesive.

7. A camera apparatus comprising:

at least one bracket that is fixed to a windshield of a vehicle from a vehicle interior side;

at least one camera case that is fixed to the bracket;

at least one camera module that is fixed to the camera case and includes a lens; and

a hood, wherein

the camera apparatus detects a position of an object present ahead of the vehicle,

the object includes a lane and another vehicle,

information on the object acquired by the camera apparatus is used for at least one of lane departure alarm control, light control, and collision avoidance control,

the camera apparatus further comprises an adjustment structure for completing adjustment of an inclination angle in a vertical direction of an optical axis of the lens with respect to the windshield by the time when the camera case is completely fixed to the bracket,

a top surface of the camera case includes a plurality of surfaces having different inclination angles,
