摘要：A lens provided on a surface of a vehicle-mounted camera has a problem that afield of view becomes undesirable because small water droplets caused by fog, light rainand others adhere and scatter incident light. In the vehicle-mounted camera provided ona periphery of a vehicle, a hydrophilic film made of silicon dioxide particles and binder isprovided on the lens surface, a mean particle diameter of silicon dioxide particlesdispersed on the lens side of the hydrophilic film is larger than a mean particle diameterof 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 ofthe silicon dioxide particles is 40 to 100 nm, and the mean particle diameter on the side incontact with air space is 10 to 15 nm.
