Abstract: A photoelectric converter comprising a resin layer that absorbs infrared light cuts out unnecessary infrared light, while the photoelectric converter has a problem that the resin layer also reduces the transmission of light in the visible range. A photoelectric converter improving the problem comprises a semiconductor substrate (2) on which photoelectric conversion elements are formed, a color filter (8) provided on the semiconductor substrate (2), and a support base (21) bonded to the color filter (8), wherein an interference filter (11) comprised of multiple thin layers of dielectric material laminated together and reflecting infrared light is provided to the support base (21). As a result, light attenuation can be minimized while infrared light is cut, and the usage efficiency of light can be increased. A photoelectric converter adjusted to the luminous efficiency of the human eye can be obtained by adjusting the light transmittance characteristics of the color filter (8) to the luminous efficiency of the human eye.
