Abstract
A vehicle-mounted imaging device that is mounted in an automobile and performs color imaging has been provided with a plurality of two-dimensionally arranged pixel cells. In each of the pixels, a color filter separates incident light by a multilayer interference filter. The multilayer interference filter is composed of two λ/4 multilayer films and a spacer layer sandwiched therebetween. The multilayer interference filter transmits light in a wavelength region that corresponds to an optical thickness of the spacer layer. The λ/4 multilayer films and spacer layer are composed of inorganic materials.
