ABSTRACT OF THE DISCLOSURE A high resistance film resistor comprises a ceramic substrate having a dielectric film coated on the outer surface of the substrate. The dielectric film has a rough surface facing away from the substrate which is sub substan- tially rougher than the surface of the substrate. The dielectric film is formed from a substantially nitrite material. A thin metal film forming a resistance element is coated on the outer rough surface of the dielectric film. The dielectric film provides a barrier against diffusion of impurities from the substrate to the resistance element and provides electrical stability to the resistance element whereby the sheet resistance of the resistance element is of a value a plurality of times greater than the sheet resistance obtained by placing the thin film directly on the supporting surface of the substrate.
