Patent attributes
In a camera apparatus, a camera case is fixed to a windshield from within a cabin of a vehicle. A camera module includes an optical unit and a camera substrate. The optical unit includes a lens. The camera substrate includes an image sensor. The optical unit includes a lens barrel portion and a base portion. The lens barrel portion holds the lens therein. The base portion has a reference surface that serves as a reference for positioning when the camera module is fixed to the camera case and to which the lens barrel portion is fixed so as to have a fixed positional relationship. The camera substrate is fixed to the optical unit in a position in which an optical axis of the lens passes through a center of a light receiving surface of the image sensor and is perpendicular to the light receiving surface of the image sensor.
