An in-vehicle camera device which is mounted on a vehicle and which captures a periphery image collected from a lens (1a), wherein the surface of the lens (a1) has a water-repellent angle that is equal to or smaller than 100 degrees, preferably equal to or smaller than 60 degrees, so that the water attached to the surface turns into a film. As a consequence, the surface of the lens (1a) exhibits higher hydrophilic properties, and when water droplets attach to the film during rainfall, the water droplets spread over the surface of the lens (1a) and form a water film. Thus, it is possible to immediately remove matter such as dirt when matter attaches to the surface of the lens (1a) and it is possible to keep the surface of the lens (1a) constantly clean. |
