Light receiving means

The present invention, by a light receiving device can receive the light in a desired wavelength band without upsizing conditions. In the light-receiving surface of light receiving means is arranged as an optical substrate, an optical substrate, a first optical multilayer film formed on an incident surface of the second optical multilayer film is formed on the opposite surface of the incident surface of the light-receiving third optical multilayer film formed on the surface. Apart from each other so that the two light transmissive wavelength band, the light shielding bands other than two bands, long wavelength light having a second wavelength band side of the two transmission wavelength band than a predetermined ratio, the light of the first wavelength band of the short wavelength side transmittance is suppressed to less than a predetermined proportion of the predetermined range.
