An imaging apparatus 10 according to one implementation of the present invention includes: a plurality of photodetectors 5a and 5b; a transparent layer 2 provided at the side of a light-receiving surface 15a, 15b of the photodetectors 5a and 5b; a plurality of spectroscopic portions 3 provided between a light-entering surface 2a of the transparent layer 2 and the photodetectors 5a and 5b; and a plurality of high refractive index transparent members 6 provided closer to the photodetectors 5a and 5b than are the spectroscopic portions 3. The high refractive index transparent members 6 have a higher refractive index than does the transparent layer 2.
