Patent attributes
A camera module is mountable to an inner side of a front windshield of a vehicle and is configured to capture an image of an external environment of the vehicle. The camera module includes an optical assembly, a camera casing, and an adhesive. The optical assembly includes an assembly reference surface for determining the position of an optical axis and captures an image of the external environment by forming an optical image incident along the optical axis from the external environment. The camera casing includes a casing reference surface to be positioned with respect to the front windshield on the outside of the camera casing and accommodates the optical assembly in a state separate from inner wall surfaces. The adhesive joins the optical assembly to the camera casing in a state in which the assembly reference surface is aligned with an imaginary plane extending along the casing reference surface.
