Abstract
A lens unit or the like with improved ability to capture proper images by reducing the likelihood that water droplets will adhere to the lens surface and change the refractive index. A surface of a lens portion () is imparted with a water-repellent property and a surface of a non-lens portion (), surrounding the lens portion (), is imparted with a hydrophilic property. As a result, if droplets on the surface of the lens portion () contact the non-lens portion (), the droplets are guided from the water-repellent surface of the lens portion () to the hydrophilic surface of the non-lens portion () thereby reducing the number of droplets residing on the lens portion ().
