A solid-state image sensor includes a semiconductor layer having photoelectric conversion portions, and a wiring structure arranged on a side of a first face of the semiconductor layer, and receives light from a side of a second face of the semiconductor layer. The wiring structure includes a reflection portion having a reflection surface reflecting light transmitted through the semiconductor layer from the second face toward the first face, toward the semiconductor layer, and an insulation film located between the reflection surface and the first face. The sensor includes a first dielectric film arranged to contact the first face, and a second dielectric film arranged between the insulation film and the first dielectric film and having a refractive index different from refractive indices of the first dielectric film and the insulation film. |
