1. A photoelectric converter comprising:
a first electrode containing a transparent conductive material;
a second electrode; and
a multilayer body that is positioned between the first electrode and the second electrode, and that has a photoelectric conversion function, wherein
the multilayer body includes a first layer and a second layer positioned between the first layer and the second electrode,
the first layer absorbs light in a first wavelength band of 360 nm or longer and transmits light in a second wavelength band, the second wavelength band including wavelengths longer than wavelengths included in the first wavelength band,
the second layer absorbs the light in the second wavelength band, and
the multilayer body substantially does not have sensitivity for photoelectric conversion in the first wavelength band and has sensitivity for photoelectric conversion in the second wavelength band.
