Abstract
A ripple is suppressed in a solid-state imaging element that obtains a spectral spectrum. The solid-state imaging element includes a surface layer, a filter layer, and a photoelectric conversion layer. In the solid-state imaging element, the surface layer has a thickness exceeding a half of a coherence length of incident light. Furthermore, in the solid-state imaging element, the filter layer transmits predetermined target light of the incident light transmitted through the surface layer and reflects a rest of the incident light transmitted through the surface layer to the surface layer. Furthermore, in the solid-state imaging element, the photoelectric conversion layer photoelectrically converts the predetermined target light transmitted through the filter layer.
