ABSTRACT:
The infrared solid-state image pickup device of the present invention comprises a light-receiving portion formed by arranging, on a transparent substrate, light-receiving elements of a plurality of types respectively including optical cavity structures with optical distances between photoelectric conversion portions and reflecting films which are different from each other by more than 100 nm. The light-receiving elements of at least one of the plurality of types having optical cavity structures whose optical distances are set such that a valley in sensitivity exists at a predetermined wavelength within a predetermined wavelength range, light within the wavelength range being photoelectrically convertible by the light-receiving elements of other types. Hence, the light-receiving portion can be divided into wavelength bands, and a structure enabling control of a wavelength sensitivity, can have, in an infrared range, a function corresponding to a complementary color detection function in a so-called visible range.
