A solid-state imaging device comprising:
- a light-receiving element;
- and
- a multilayer film which is disposed on a side of a light-receiving surface of the light-receiving element and is formed by laminating a plurality of layers made of materials having different refractive indices, in which a defect layer is included in at least one of the laminated layers,
- wherein in the defect layer,
- a plurality of kinds of materials having different refractive indices coexist in a surface parallel to the light-receiving surface,
- a ratio of areas of the materials coexisting in the surface is set based on the wavelength of light reaching the light-receiving element, and
- the ratio of areas of the materials is different at different positions which are respectively located closer to a central portion and a periphery of an effective imaging region that is formed by each of the light-receiving elements.
