The photoelectric conversion element is provided with a light-absorbing member comprising a light-absorbing material capable of absorbing monochromatic light at wavelength λ0 and generating a carrier, and a substantially collimated light beam comprising the monochromatic light is used as the input light. The photoelectric conversion element has a band-pass filter formed on the side wherefrom the input light comprising the monochromatic light enters with an incident angle &thetas;, the band-pass filter having a function of transmitting selectively light of wavelength λ0 at least. In addition, the light-absorbing member is provided with a diffuse reflective surface on the back side thereof. |
