In a monochrome sensor, a sensor unit is covered with a protective film, and a light-transmitting organic film is formed on this protective film. Consequently, ripples in the spectral sensitivity characteristics are reduced. Even if the positions of the peaks and valleys of these ripples vary due to variations in the thicknesses of the protective film and the organic film or due to effective variations in these film thicknesses caused by the difference in the incident angle of light, a variation in the sensitivity at a given wavelength is small. This results in a small variation in the wavelength at which the maximum value of the spectral sensitivity is obtained and a small variation in the sensitivity derived from the difference in the incident angle of light.
A monochrome sensor, wherein a light-transmitting film is formed directly on top of a protective film without any layers of intervening material disposed therebetween, the protective film covering at least a sensor unit without any layers of intervening material disposed therebetween, said light-transmitting film forming an external light-incident surface for said sensor without any layers of material disposed on top of the light-transmitting film, whereby variations in the wavelength of the maximum spectral sensitivity of said sensor are reduced by said light-transmitting film.
