| Zusammenfassung: | A solid-state imaging device includes: light-receiving elements; and first dispersive elements on a light-incident side of the light-receiving elements. Each first dispersive element includes first and second light transmissive film materials. The second light transmissive film material has a refractive index that is lower than that of the first light transmissive film material in a first wavelength range and higher than that of the first light transmissive film material in a second wavelength range longer in wavelength than the first wavelength range. A volume occupation ratio of the first light transmissive film material in each dispersive element increases from one end towards the other end of the dispersive element in a direction parallel to a light-receiving surface, while a volume occupation ratio of the second light transmissive film material in the dispersive element increases from the other end towards the one end in the direction. |
