Abstract
Provided is a solid-state imaging device capable of improving sensitivity of near-infrared wavelengths and suppressing color mixing without being restricted by a wiring layout. A solid-state imaging device includes: a substrate on which a plurality of photoelectric conversion units are formed corresponding to different light wavelengths; a wiring layer including a transistor on a surface opposite to a surface on a light incident side of the substrate and on a photoelectric conversion unit side to execute signal processing on a charge output from the photoelectric conversion unit and a wiring on a side opposite to the photoelectric conversion unit side of the transistor to transfer an electrical signal obtained by the transistor; and a reflection design film on a transistor side from at least a junction between the substrate and the wiring layer, which has higher reflectivity than the wiring layer and reflects a vertical component of incident light.
