1. A solid-state imaging element, comprising:
a surface layer that has a thickness exceeding a half of a coherence length of incident light, wherein
the surface layer includes an antireflection film, a transparent resin layer, and a stress relaxation layer, and
the transparent resin layer is between the antireflection film and the stress relaxation layer;

a filter layer configured to transmit a first part of the incident light transmitted through the surface layer and reflect a second part of the incident light transmitted through the surface layer to the surface layer, wherein the second part of the incident light transmitted through the surface layer is different from the first part of the incident light transmitted through the surface layer; and
a photoelectric conversion layer configured to photoelectrically convert the first part of the incident light transmitted through the filter layer.
