Abstract: A technique for improving the visibility of images from an imaging device even in conditions such that waterdrops adhering on a surface of a lens is very small is provided. An imaging device 13 includes a camera 20 having a lens 23, in which a lens side hydrophilic layer 23a is applied on a surface of the lens 23, and being configured to be provided to a vehicle, and a waterdrop guiding part 21 which guides waterdrops that adhere on the vehicle to the lens 23.

Abstract: A lens provided on a surface of a vehicle-mounted camera has a problem that a field of view becomes undesirable because small water droplets caused by fog, light rain and others adhere and scatter incident light. In the vehicle-mounted camera provided on a periphery of a vehicle, a hydrophilic film made of silicon dioxide particles and binder is provided on the lens surface, a mean particle diameter of silicon dioxide particles dispersed on the lens side of the hydrophilic film is larger than a mean particle diameter of silicon dioxide particles on the side in contact with air space outside the vehicle-mounted camera. The mean particle diameter on the side affixed to the lens side out of the silicon dioxide particles is 40 to 100 nm, and the mean particle diameter on the side in contact with air space is 10 to 15 nm.
